Nuclear Issues

Russia's 2022 invasion of Ukraine illuminated the long profound shadow of nuclear weapons over international security. Russia's nuclear threats have rightfully garnered significant attention because of the unfathomable lethality of nuclear weapons. However, the use of such weapons in Ukraine is only one way—albeit the gravest— that Russia could challenge the global nuclear order. Russia's influence extends deep into the very fabric of this order—a system to which it is inextricably bound by Moscow's position in cornerstone institutions such as the Nuclear Non-Proliferation Treaty (NPT) and the International Atomic Energy Agency (IAEA). From withdrawing from key treaties to stymieing resolutions critical of misconduct, Moscow has demonstrated its ability to challenge the legitimacy, relevance, and interpretations of numerous standards and principles espoused by the West.

In light of Russia’s annexation of Crimea and its current threat to Ukrainian sovereignty, it’s fair to ask: What is the significance now of the Budapest Memorandum?

The Biden-Putin summit in Geneva did not disappoint the very low expectations set out for it. To move beyond symbolism and signaling, however, the Biden-Putin proclamation has to be translated into practical progress.

No great breakthroughs or dramatic developments were expected at the Biden-Putin summit, and none was achieved. But the message was clear: There is a new sheriff in town. Putin noticed, describing Biden as very different from Trump—experienced, balanced, and professional.

In the authors' view, neither formal NATO membership nor nuclear weapons are fitting security options for Ukraine in the face of Russian aggression. To secure its borders and achieve sustainable peace and stability in Europe, Ukraine should forge a treaty-based strategic alliance directly with the United States.

The administration of President Donald J. Trump has consistently used fear of China to undermine nearly five decades of bipartisan consensus on US–Russian nuclear arms control. The negative consequences of these actions may last far beyond the Trump presidency. If generations of agreement between Democrats and Republicans on bilateral nuclear treaties with Russia erode, it will pose a significant setback to US national security and global stability. Future leaders may ultimately need to consider new approaches to nuclear risk reduction that preserve the benefits of the arms control regime.

The Bulletin of Atomic Scientists has published a document from the Pugwash Conference on Science and World Affairs concerning nuclear problems and tensions in the time of COVID-19. The document has been co-signed by a large number of Pugwash colleagues and personalities.

Putin is rumored to prefer focusing on foreign policy, where the Kremlin has proved itself to be a skilled player, while finding structural problems at home too boring to focus on. However, unless these are solved, he or his successor will continue to confront the reality that Russia remains too far behind the United States and China economically and demographically to be a true peer to these countries in the changing global order.

As we are all well aware, the original Cold War, which officially ended 40 years ago this month, featured a number of close calls that almost turned it into a hot war. Thankfully, neither the Cuban Missile Crisis of 1962 nor the Able Archer exercise of 1983 (nor any other perilous incidents), led to a war between Washington and Moscow. More recently, however, respected statesmen have again begun to sound alarms. “Not since the 1962 Cuban Missile Crisis has the risk of a U.S.-Russian confrontation involving the use of nuclear weapons been as high as it is today,” former U.S. Energy Secretary Ernest Moniz and former U.S. Sen. Sam Nunn warned in a recent article in Foreign Affairs. I have expressed some doubts about this proposition, but it is nevertheless worth asking what it is—other than the fear of mutually assured destruction—that keeps the U.S. and Russia from stumbling into a war today or tomorrow. Part of the answer lies in the bilateral and multilateral agreements specifically designed to prevent incidents that could escalate into a war.
