On Tuesday [June 4], the House Subcommittee on Strategic Forces debated the draft Fiscal Year 2020 National Defense Authorization Act.

It voted out, on party lines, language that prohibits deployment of a low-yield warhead on the Trident D5 submarine-launched ballistic missile.  That makes sense:  The rationale for the warhead is dubious, and the weapon likely would never be selected for use.

27 April 2019 marked the first anniversary of the historic Panmunjom summit between North Korean leader Kim Jong-un and South Korean leader Moon Jae-in.

The meeting jumpstarted the whirlwind of North Korea’s summit diplomacy and prompted a new wave of hope that diplomacy could be effective after years of confrontation and tensions.

But the anniversary was marked with mixed messages and dissonant attitudes — it was celebrated by the South Koreans alone. North Korea remained unresponsive to the South’s invitation to the anniversary ceremony, and North Korea’s Committee for the Peaceful Reunification of the Country openly demanded that the South explore ‘more active measures’ to improve inter-Korean ties. The inter-Korean rapprochement efforts borne out of Panmunjom are stranded by the stalemate on the nuclear track...

For nearly five decades, Washington and Moscow have engaged in negotiations to manage their nuclear competition. Those negotiations produced a string of acronyms—SALT, INF, START—for arms control agreements that strengthened strategic stability, reduced bloated nuclear arsenals and had a positive impact on the broader bilateral relationship.

That is changing. The Intermediate-range Nuclear Forces (INF) Treaty is headed for demise. The New Strategic Arms Reduction Treaty (New START) has less than two years to run, and the administration of Donald Trump has yet to engage on Russian suggestions to extend it. Bilateral strategic stability talks have not been held in 18 months.

On its current path, the U.S.-Russia nuclear arms control regime likely will come to an end in 2021. That will make for a strategic relationship that is less stable, less secure and less predictable and will further complicate an already troubled bilateral relationship.

Fifty Years of Arms Control

Bilateral nuclear arms control talks between Washington and Moscow began in 1969 with the Strategic Arms Limitation Talks (SALT). They resulted from a growing understanding that negotiated limits on the superpowers’ nuclear arms competition served the interests of both. Over the next five decades, arms control treaties and unilateral force decisions led the sides to reduce their active arsenals to 4,000-4,500 nuclear weapons each—down from a U.S. peak of more than 30,000 in the 1960s and a Soviet/Russian peak that exceeded 40,000 in the 1970s.

Early treaties such as the 1972 Interim Offensive Agreement and the 1979 SALT II Treaty (which never entered into force but whose limits were observed into the mid-1980s) merely slowed the growth of nuclear arsenals. Later treaties had a more dramatic impact. The 1987 INF Treaty banned the entire class of U.S. and Soviet land-based missiles with ranges between 500 and 5,500 kilometers. The 1991 START Treaty required the sides to reduce their accountable strategic nuclear warheads by some 40 percent while cutting strategic missile launchers and bombers by about 30 percent.

Arms control agreements often had a beneficial impact on the broader relationship. SALT helped advance détente in the early 1970s; progress on INF and START spurred an improvement in the overall U.S.-Soviet relationship in the late 1980s; and the relatively quick conclusion of New START gave a positive impulse to the Obama administration’s reset with Russia, even though the reset proved short-lived.

Today, the U.S.-Russian relationship has hit its lowest point since the end of the Cold War. Arms control, or the looming collapse of arms control, rather than helping, may contribute to a further deterioration of relations.

The Demise of the INF Treaty

The INF Treaty is on a death course. Russia violated the treaty by developing and deploying the 9M729, a prohibited intermediate-range cruise missile. Neither the Obama nor the Trump administration employed an effective strategy to persuade Moscow to return to compliance.

On October 20, 2018, President Trump announced that the United States would terminate the treaty, surprising allies and administration officials alike. NATO subsequently backed the U.S. decision, though European officials privately grumbled about a fait accompli. In early February, U.S. officials stated that they had suspended U.S. treaty obligations and given Russia the required six months’ notice of the U.S. intention to withdraw from the agreement. Russia then suspended its treaty obligations.

The United States could not remain forever in a treaty that Russia has violated. However, the way the Trump administration handled its departure amounted to diplomatic malpractice. Washington will get blamed for the treaty’s end.

There was a smarter way. First, U.S. officials should have informed their European counterparts in early 2018 that the United States would have no choice in 12–24 months but to leave the treaty if Russia did not correct its violation and urge them to apply political heat on the Kremlin, including at the highest level. Russia’s intermediate-range missiles cannot reach the United States; they threaten Europe and Asia.

Second, the U.S. military should have deployed conventionally armed air- and sea-launched cruise missiles to the European region to show that the Russian violation would not go unchallenged.

Third, NATO should have begun a study of long-term countermeasures, with one option being deployment in Europe of a conventionally armed U.S. intermediate-range ballistic missile. While the Alliance likely could not have found consensus to adopt that option, discussing it would have reminded military leaders in Moscow how much they disliked the U.S. Pershing II, whose deployment in West Germany in the 1980s proved key to securing the INF Treaty.

Fourth, U.S. officials should have indicated to their Russian counterparts that, if they addressed U.S. concerns about the 9M729 violation, the United States would consider ways to address Russian concerns that the Aegis Ashore missile defense facility in Romania could launch offensive missiles.

Would such steps have brought Russia back into compliance? Perhaps not, but they certainly would have increased the odds. Even if they did not succeed, they would have positioned Washington far better with its allies and put it in a stronger position to lay blame for the treaty’s end where it belonged—on Russia.

In the actual event, the Trump administration hardly tried. In January, Russian officials offered to exhibit the 9M729 to U.S. experts. U.S. officials could have taken that proposal and insisted on procedures for a meaningful exhibition. Instead, they flat out turned it down.

Much of the problem on the American side may lie with National Security Advisor John Bolton. He generally disdains arms control agreements as constraining U.S. capabilities and options (which is true, but they also constrain Russian capabilities and options). He had previously called for U.S. withdrawal from the INF Treaty.

Exhibitions of the 9M729 and Aegis Ashore facility could have opened a path to resolve each side’s compliance concerns, but Moscow and Washington have not shown the needed political will. It looks like the treaty will meet its demise in August.

Questions about the Future of New START

In contrast to the INF Treaty, Russia has complied with the limits of the 2010 New START Treaty, which required reductions by each country to no more than 1,550 deployed strategic warheads and no more than 700 deployed strategic missiles and bombers by February 2018. The United States also met the limits, though Russian officials question the adequacy of measures the U.S. military took to remove some strategic systems from treaty accountability.

New START by its terms will expire in February 2021, though the treaty allows extension for up to five years. Russian officials have proposed discussion of extension. In 2017, Trump administration officials said they would first have to complete the new nuclear posture review and see whether Russia met the February 2018 limits. Both of those boxes were checked more than a year ago. U.S. officials now say they are studying the question and see no rush.

New START extension should be a no-brainer. First, it would extend to 2026 the limits on Russian strategic forces and provide a mechanism to address new nuclear systems that the Russian military has under development. Second, extension would not affect U.S. strategic modernization plans, which the Pentagon designed to fit within New START’s limits. Third, extension would continue the flow of information that the U.S. military and intelligence community receive about Russian strategic forces from data exchanges, notifications and on-site inspections. That information lets the U.S. military make smarter decisions about how to equip and operate U.S. strategic forces.

When asked about extension, however, Bolton has raised two alternatives: renegotiation of New START or a treaty modeled on the 2002 Strategic Offensive Reductions Treaty (SORT). Neither holds much promise.

Renegotiation would allow Washington to try to improve New START, perhaps with additional verification measures or expanded limits to capture nuclear weapons not now covered by the treaty. But Moscow would seek changes as well, starting with limits on missile defense and conventional strike systems, both of which are anathema to the Trump administration. Renegotiation would take a long time and have, at best, an uncertain prospect of success.

As for the SORT model, SORT limited just warheads (though with no verification measures); it did not constrain strategic missiles and bombers. While Moscow accepted such an agreement in 2002, Russian officials since 2008 have made clear that a strategic arms control agreement must limit missiles and bombers, as does New START.

Bolton opposed New START when the Senate discussed its ratification back in 2010. Neither Secretary of State Mike Pompeo nor Acting Secretary of Defense Patrick Shanahan seem to be advocates for the treaty. Although extension would be very much in the U.S. interest, the Trump administration appears inclined to let it expire.

No Strategic Stability Talks

U.S. and Russian officials in the past have held strategic stability talks to take a broad look at developments that affect their strategic relationship. Such talks are useful, particularly when new developments, such as those in the cyber and space domains, emerge and when Russian nuclear doctrine has provoked concern in Washington and led to changes in the U.S. nuclear posture. Even if strategic stability talks do not spin off specific negotiations, they provide a venue for the sides to exchange views and better understand the concerns of the other.

During the Trump administration, a one-day session of strategic stability talks took place in September 2017. As of March 2019, it has not agreed to a second meeting.

An Unsettling Future

For most of the five decades of U.S.-Soviet/Russian arms control negotiations, the American side took the lead. Moscow often struck a pose not of disinterest, but of less interest—likely for bargaining purposes. That is no longer the case. The Kremlin now faces a White House that attaches as little priority to reducing arms as it does—perhaps less. The U.S. President evinces no understanding of arms control, while his national security advisor apparently seeks to end it.

With the INF Treaty all but dead, New START’s fate uncertain after 2021 and no sign of new initiatives on either side, arms control as practiced for some 50 years may be coming to an end or, at a minimum, to a pause. That occurs at a time when Russia and the United States have significant nuclear modernization programs underway. While the bulk of those programs aim primarily to replace old weapons with new ones, the sides are also developing nuclear capabilities that neither previously had in its arsenal. Economic constraints may limit an all-out arms race, but the strategic nuclear relationship seems headed for uncharted territory.

The end of the U.S.-Russian nuclear arms control regime would have wider impacts. If the two nuclear superpowers no longer are reducing—and no longer limiting—their nuclear arms, what credibility will they have to insist that other countries, such as North Korea, forgo nuclear weapons or that third countries sanction proliferating states? Will China decide to adjust its nuclear posture and move from its current modest stockpile of under 300 weapons toward a larger and more diverse arsenal?

The current course will lead to a less stable and secure world. The United States and Russia will be less able to predict future developments on the other side and thus will have to make expensive worst-case assumptions. It will make for a more complex and dangerous relationship. Perhaps then they will recall the lessons of the 1960s and 1980s that arms control, however imperfect, can offer a useful tool for managing great power competition.

March 18 marks the fifth anniversary of Russia’s illegal annexation of Crimea, which capped the most blatant land grab in Europe since World War II. While the simmering conflict in Donbas now dominates the headlines, it is possible to see a path to resolution there. It is much more difficult with Crimea, which will remain a problem between Kyiv and Moscow, and between the West and Russia, for years—if not decades—to come.

THE TAKING OF CRIMEA

In late February 2014, just days after the end of the Maidan Revolution and Victor Yanukovych’s flight from Kyiv, “little green men”—a term coined by Ukrainians—began seizing key facilities on the Crimean peninsula. The little green men were clearly professional soldiers by their bearing, carried Russian weapons, and wore Russian combat fatigues, but they had no identifying insignia. Vladimir Putin originally denied they were Russian soldiers; that April, he confirmed they were.

By early March, the Russian military had control of Crimea. Crimean authorities then proposed a referendum, which was held on March 16. It proved an illegitimate sham. To begin with, the referendum was illegal under Ukrainian law. Moreover, it offered voters two choices: to join Russia, or to restore Crimea’s 1992 constitution, which would have entailed significantly greater autonomy from Kyiv. Those on the peninsula who favored Crimea remaining a part of Ukraine under the current constitutional arrangements found no box to check.

The referendum unsurprisingly produced a Soviet-style result: 97 percent allegedly voted to join Russia with a turnout of 83 percent. A true referendum, fairly conducted, might have shown a significant number of Crimean voters in favor of joining Russia. Some 60 percent were ethnic Russians, and many might have concluded their economic situation would be better as a part Russia.

It was not, however, a fair referendum. It was conducted in polling places under armed guard, with no credible international observers, and with Russian journalists reporting that they had been allowed to vote. Two months later, a member of Putin’s Human Rights Council let slip that turnout had been more like 30 percent, with only half voting to join Russia.

Regardless, Moscow wasted no time. Crimean and Russian officials signed a “treaty of accession” just two days later, on March 18. Spurred by a fiery Putin speech, ratification by Russia’s rubberstamp Federation Assembly and Federation Council was finished by March 21.

ATTEMPTS TO JUSTIFY

Moscow’s actions violated the agreement among the post-Soviet states in 1991 to accept the then-existing republic borders. Those actions also violated commitments to respect Ukraine’s sovereignty, territorial integrity, and independence that Russia made in the 1994 Budapest Memorandum on Security Assurances for Ukraine and 1997 Ukrainian-Russian Treaty of Friendship, Cooperation and Partnership.

In late March 2014, Russia had to use its veto to block a U.N. Security Council resolution that, among other things, expressed support for Ukraine’s territorial integrity (there were 13 yes votes and one abstention). The Russians could not, however, veto a resolution in the U.N. General Assembly. It passed 100-11, affirming Ukraine’s territorial integrity and terming the Crimean referendum invalid.

Russian officials sought to justify the referendum as an act of self-determination. It was not an easy argument for the Kremlin to make, given the history of the two bloody wars that Russia waged in the 1990s and early 2000s to prevent Chechnya from exercising a right of self-determination.

Russian officials also cited Western recognition of Kosovo as justification. But that did not provide a particularly good model. Serbia subjected hundreds of thousands of Kosovar Albanians to ethnic-cleansing in 1999; by contrast, no ethnic-cleansing occurred in Crimea. Kosovo negotiated with Serbia to reach an amicable separation for years before declaring independence unilaterally. There were no negotiations with Kyiv over Crimea’s fate, and it took less than a month from the appearance of the little green men to Crimea’s annexation.

The military seizure of Crimea provoked a storm of criticism. The United States and European Union applied visa and financial sanctions, as well as prohibited their ships and aircraft from traveling to Crimea without Ukrainian permission. Those sanctions were minor, however, compared to those applied on Russia after it launched a proxy conflict in Donbas in April 2014, and particularly after a Russian-provided surface-to-air missile downed a Malaysian Air airliner carrying some 300 passengers.

Whereas Ukrainian forces on Crimea did not resist the Russian invasion (in part at the urging of the West), Kyiv resisted the appearance of little green men in Donbas. Before long, the Ukrainians found themselves fighting Russian troops as well as “separatist” forces. That conflict is now about to enter its sixth year.

Finding a settlement in Donbas has taken higher priority over resolving the status of Crimea—understandable given that some 13,000 have died and two million been displaced in the fighting in eastern Ukraine. Moscow seems to see the simmering conflict as a useful means to pressure and distract Kyiv, both to make instituting domestic reform more difficult and to hinder the deepening of ties between Ukraine and Europe.

Resolving the Donbas conflict will not prove easy. For example, the Kremlin may not be prepared to settle until it has some idea of where Ukraine fits in the broader European order, that is, its relationship with the European Union and NATO. But Russia has expressed no interest in annexing Donbas. While the seizure of Crimea proved very popular with the broader Russia public, the quagmire in Donbas has not. The most biting Western economic sanctions would come off of Russia if it left Donbas. At some point, the Kremlin may calculate that the costs outweigh the benefits and consent to a settlement that would allow restoration of Ukrainian sovereignty there.

Moscow will not, on the other hand, willingly give up Crimea. Russians assert a historical claim to the peninsula; Catherine the Great annexed the peninsula in 1783 following a war between Russia and the Ottoman Empire. (That said, Crimea was transferred from the Russian Soviet Federative Socialist Republic to the Ukrainian Soviet Socialist Republic in 1954, and, as noted above, the republics that emerged from the wreckage of the Soviet Union in 1991 agreed to accept the borders as then drawn.)

Retaining Crimea is especially important to Putin, who can offer the Russian people no real prospect of anything other than a stagnant economy and thus plays the nationalism and Russia-as-a-great-power cards. He gained a significant boost in public popularity (much of which has now dissipated) from the rapid and relatively bloodless takeover of the peninsula. Moreover, it offers a vehicle for Russia to maintain a festering border dispute with Ukraine, which the Kremlin may see as discouraging NATO members from getting too close to Ukraine.

Kyiv at present lacks the political, economic, and military leverage to force a return. Perhaps the most plausible route would require that Ukraine get its economic act together, dramatically rein in corruption, draw in large amounts of foreign investment, and realize its full economic potential, and then let the people in Crimea—who have seen no dramatic economic boom after becoming part of Russia—conclude that their economic lot would be better off back as a part of Ukraine.

For the West, Russia’s seizure and annexation of Crimea pose a fundamental challenge to the European order and the norms established by the 1975 Helsinki Final Act. The United States and Europe should continue their policy of non-recognition of Crimea’s illegal incorporation. They should also maintain Crimea-related sanctions on Russia, if for no other reason than to signal that such land grabs have no place in 21st-century Europe.

On January 18, 2019, Stanford Global Studies and the Stanford Program on International and Cross-Cultural Education (SPICE) hosted a book talk by Professor Michael McFaul. McFaul served for five years in the Obama administration, first as Special Assistant to the President and Senior Director for Russian and Eurasian Affairs at the National Security Council (2009–2012), and then as U.S. Ambassador to the Russian Federation (2012–2014). He is also one of several contributing scholars to Inside the Kremlin, SPICE’s lesson plan on Soviet and Russian history. McFaul’s talk was given to approximately 30 community college and secondary school educators from the San Francisco Bay Area. Three of the educators—Nancy Willet, Phillip Tran, Don Uy-Barreta—are 2018–19 Stanford Education Partnership for Internationalizing Curriculum (EPIC) Fellows, and this article highlights their reflections.

Ambassador McFaul has described From Cold War to Hot Peace as “three books in one.” First, it is a book that explains the arc of U.S.–Russia relations since the end of the Cold War. Second, it a book that describes the “reset” in U.S.–Russia relations and its aftermath during the Obama presidency. Third, it is a book about McFaul’s life that describes how his involvement with the debate team at Bozeman High School, Montana, sparked his interest in Russia and led to his subsequent study of Russia at Stanford University, Oxford University, and in Russia itself. During his talk, he touched upon all three.

McFaul’s reflections not only provided the educators with important content on U.S.–Russia relations and insights from his youth to his ambassadorship, but also prompted the educators to consider effective teaching and pedagogical strategies. McFaul’s use of storytelling, presentation of multiple perspectives, emphasis on interdisciplinarity, and sharing of first-hand accounts gave the educators a glimpse into McFaul not only as an academic and diplomat but as a teacher.

EPIC Fellow Nancy Willet, Co-chair of the Business & Information Systems Department, College of Marin, noted, “I was most impressed with Ambassador McFaul’s engaging storytelling. His first-hand insights of his time spent studying and working in Russia challenged some of my misguided assumptions and helped expand my understanding of the complexities of U.S.–Russia relations. I grew up during the Cold War and the Ambassador disrupted some of my deep-rooted misconceptions about the former Soviet Union and further opened my mind for a more nuanced understanding.” In a follow-up communication, Willet said that she is devouring From Cold War to Hot Peace and plans to share McFaul’s scholarly insights with her law students—particularly when discussing democracy and rule of law—here and abroad.

EPIC Fellow Philip Tran, Instructor of Business, San Jose City College, remarked that “Ambassador McFaul’s talk reinforced the complicated notion of human relations and the importance of an interdisciplinary study of it—including political science, business, economics, etc. Interdisciplinarity is a key to grasping a better understanding of human relations.” He continued by noting that the biggest take-away from McFaul’s talk was that it cautioned him as a teacher to “refrain from the natural ‘knee-jerk’ reactions and to seek a deeper understanding of the situation from all sides…. Even though Ambassador McFaul is a subject matter expert on U.S.–Russian relations, he displayed humility and acceptance of ambiguity in his responses to some of the toughest questions regarding the U.S. relationship with Russia and Vladimir Putin.”

EPIC Fellow Don Uy-Barreta, Instructor of Economics, De Anza College, reflected upon the significance of sharing first-hand experiences with students. He noted that “Reading about Ambassador McFaul’s experience is very informative, but being able to ask questions and hearing it from the source is a whole different level of experience. As he was telling us about his days in Russia, it felt like I was right next to him, and it gave me goosebumps.” Uy-Barreta found inspiration in McFaul’s talk as he prepares for his presentation on global economics at the EPIC Symposium on May 18, 2019 during which the 2018–19 EPIC Fellows will present their research at Stanford.

McFaul has given numerous talks on From Cold War to Hot Peace but this was the first geared to an audience of educators. As I observed his talk, I was primarily attentive to the pedagogical strategies that he utilized to engage the educators. For me, his effective teaching made the history and insights in From Cold War to Hot Peace come alive and feel more like “four books in one.”

This book talk was made possible by a U.S. Department of Education Title VI grant that provides professional development opportunities for K–12 teachers and community college instructors. Among these opportunities is EPIC, a program that provides one-year fellowships to community college instructors. Title VI grant collaborators include Stanford Global Studies (SGS), SPICE, Lacuna Stories, and the Stanford Graduate School of Education’s Center to Support Excellence in Teaching. SGS’s Denise Geraci and SPICE’s Jonas Edman organized and facilitated the talk by Ambassador McFaul.

SPICE also offers professional development opportunities for middle school teachers and high school teachers. To stay informed of SPICE news, join our email list or follow us on Facebook and Twitter.

Following the abrupt ending of the highly anticipated second bilateral summit between President Donald Trump and North Korean leader Kim Jong-un in Hanoi, APARC and CISAC scholars evaluate the result of the summit, its implications for regional relations in Northeast Asia, and the opportunities moving forward towards the goal of denuclearization of the Korean peninsula.

This Q&A with Noa Ronkin features Andray Abrahamian, the 2018-19 Koret Fellow in Korean Studies at APARC, whose work with the nonprofit Choson Exchange has taken him to the DPRK nearly 30 times; Siegfried S. Hecker, top nuclear security expert, former Director of the Los Alamos National Laboratory, Research Professor of Management Science and Engineering, Emeritus, and Senior Fellow at CISAC/FSI, Emeritus; and Gi-Wook Shin, Professor of Sociology, William J. Perry Professor of Contemporary Korea, Director of APARC, and founding Director of the Korea Program.

President Trump caught the world by surprise once again yesterday with a decision not to sign a deal with his North Korean counterpart, Chairman Kim Jong-un, in Hanoi, Vietnam. While walking away is a common tactic in working-level negotiation, what happened in Hanoi was a rare case and the least expected outcome.

Trump and Kim share a common desire for development.

At first glance U.S. President Donald Trump and North Korean leader Kim Jong Un seem like an unlikely pair. A few years back they were calling each other “Rocket Man” and a “dotard,” and tension between the United States and North Korea was escalating rapidly in 2017. But in a few days they are slated to meet for the second time, and according to Trump they had “fallen in love” not long after their first encounter. What could have created such intimate bond between the two? The common interest that brings the two together is the desire for development — economic development in the case of Kim and property development in the case of Trump.

This piece originally appeared at Brookings.

The Trump administration has finished off the 1987 Intermediate-range Nuclear Forces (INF) Treaty, a treaty mortally wounded by Russia’s deployment of a banned intermediate-range missile. That leaves the 2010 New Strategic Arms Reduction Treaty (New START) as the sole agreement limiting U.S. and Russian nuclear forces.

New START has less than two years to run. At the February 15-16 Munich Security Conference, a senior Russian official reiterated Moscow’s readiness to extend the treaty. The administration, however, continues its odd reluctance to take up that offer. House Democrats should use their power of the purse on the issue.

WHY EXTENSION MAKES SENSE

Signed in 2010, New START limits the United States and Russia each to no more than 700 strategic ballistic missiles and bombers, and no more than 1,550 deployed strategic warheads. Those limits took full effect in February 2018. Both sides have complied, although technical questions have arisen. Russian officials question the way in which the U.S. military converted some launchers so that they would not count.

By its terms, New START runs until February 5, 2021. It can be extended for up to five years by simple agreement between the U.S. and Russian presidents.

When asked about extension in 2017, administration officials said they would wait to complete the nuclear posture review and to see if the Russians met the New START limits. Both of those boxes were checked more than a year ago. Administration officials now say they are studying extension but see no need to rush.

New START extension is in the U.S. interest.

First, extension would constrain Russian strategic nuclear forces until 2026. It makes little sense to let the treaty lapse in 2021, when Russia has hot production lines churning out new missiles, submarines, and bombers.

Second, New START extension would not impact U.S. strategic modernization plans. They are sized to fit within New START’s limits. Moreover, the United States will not start producing significant numbers of replacement missiles, submarines, and bombers until the second half of the 2020s.

Third, extension would continue the flow of information that the sides share with each other about their strategic forces. That comes from data exchanges, notifications, on-site inspections and other verification measures, all of which end if New START lapses. Making up for that loss of information would require a costly investment in new national technical means such as reconnaissance satellites.

WHY WE SHOULD WORRY

Extension should be a no-brainer. However, in a White House that operates on its own facts and at times with an indecipherable logic, extension is not a given.

President Trump does not seem to understand much about nuclear arms control. During his first telephone conversation with President Putin, Trump reportedly dismissed New START as a bad deal done by his predecessor. He has taken delight in undoing the accomplishments of President Obama (witness the Iran nuclear accord).

National Security Advisor Bolton shows disdain for arms control and has criticized New START. One of its faults, according to Mr. Bolton: It provides for equal limits on the United States and Russia. He felt the treaty should allow the U.S. military to have more. (U.S. diplomats would have had an interesting time trying to negotiate that.) Asked about New START extension, Mr. Bolton notes two alternatives: renegotiation and a new treaty modeled on the 2002 Strategic Offensive Reductions Treaty (SORT).

Renegotiation would allow U.S. officials to try to improve New START, perhaps with more intrusive verification measures, or even broadening the agreement to cover non-strategic nuclear weapons. Moscow, however, would seek changes as well, such as constraints on missile defenses—anathema to Washington.

Renegotiation would prove difficult, take considerable time, and have at best uncertain prospects for success. A wiser course would extend New START and then seek a renegotiation or a new follow-on treaty.

As for SORT, negotiated by Mr. Bolton, it limited deployed warheads only. Mr. Putin accepted that in 2002, but Russian officials have long since made clear that limits should apply to warheads and delivery vehicles, as they do in New START.

SORT, moreover, was “sort of” arms control. Lacking agreed definitions, counting rules or monitoring measures, it was unverifiable. In doing their own counts on the honor system, the U.S. and Russian militaries may not have even counted the same things.

Neither Secretary of State Pompeo nor Acting Secretary of Defense Patrick Shanahan has shown interest in championing New START. The uniformed military leadership argued the treaty’s value in the past, but Chairman of the Joint Chiefs Joseph Dunford recently has hedged.

While ratification of a treaty requires consent from two-thirds of the Senate, the president alone can decide to leave a treaty. The Trump administration did not consult with either Congress or allies on withdrawal before Trump announced his intention to pull out of the treaty last October.

HOUSE DEMOCRATS TO THE RESCUE?

While the Trump administration shows little interest in arms control, it does want funding to modernize U.S. strategic forces. Democrats should recognize that and force the White House’s hand.

The U.S. strategic triad is aging. Ballistic missile submarines are the leg of the triad most in need of urgent replacement. They should be funded. Replacing intercontinental ballistic missiles (ICBMs) or building the B-21 bomber, however, are less urgent needs. As they work on the appropriations for the 2020 defense budget, House Democrats should make clear to the White House and the Pentagon that money for ICBM modernization or the B-21 would need to be paired with extension of New START. That will get attention.

Retaining a strategic triad makes sense (though the need for 400 deployed ICBMs is debatable). Retaining New START makes sense as well. House Democrats should simply insist on a trade.
