To Enhance National Security, the Biden Administration Will Have to Trim an Exorbitant Defense Wish List

| Mar. 13, 2024

David Kearn argues that even in the absence of restrictive resource and budgetary constraints, a focus on identifying and achieving concrete objectives that will position the United States and its allies to effectively deter aggression in critical regional flashpoints should be the priority given the stressed nature of the defense industrial base and the nuclear enterprise.

This year's G7 summit in Hiroshima sees nuclear disarmament and non-proliferation sitting high on the agenda, amid rising tensions between the nuclear states and an increasingly divided international order.  Six contributors offer their analyses, including the Belfer Center's Mayumi Fukushima.

The Dueling Nuclear Nightmares Behind the South Korean President’s Alarming Comments

| Jan. 25, 2023

Earlier this month, South Korean President Yoon Suk-yeol set off alarms. In an off-the-cuff remark, he warned that Seoul might need to develop nuclear weapons—or demand redeployment of U.S. nuclear arms to the Korean Peninsula—to counter North Korean nuclear threats. In doing so, Yoon spotlighted a popular view once reserved for hawkish commentators, defense intellectuals, and former military officials. Keeping nuclear weapons out of South Korea will ultimately be a U.S. responsibility that requires addressing both the deteriorating security environment and the domestic drivers underlying Yoon’s statement.

Was Ukraine Wrong to Give Up Its Nukes?

| Apr. 08, 2022

Although Russia has relied exclusively on conventional weapons for its invasion of Ukraine, behind the scenes lurks Moscow’s massive nuclear arsenal. Hours before Russian forces crossed into Ukraine, Russian President Vladimir Putin reminded the world that his country was “one of the most powerful nuclear states” and that anyone who interfered with his war in Ukraine or threatened Russia directly would face “consequences that you have never faced in your history.” Three days later, as global outrage grew, Putin ordered Russia’s nuclear forces to a higher level of readiness. Even without these explicit threats, Russia’s nuclear deterrent would have prevented Western countries from intervening in Ukraine. Beyond supplying Kyiv with anti-armor and light air defense weapons, they will not come to Ukraine’s defense for fear of nuclear escalation, as U.S. President Joe Biden and other NATO leaders have made abundantly clear. Now that Putin’s attempts to seize Kyiv have been thwarted, there is a risk he will use tactical nuclear weapons to bring Ukraine to its knees. And while this scenario remains unlikely, neither Ukraine nor NATO can do anything to prevent it from happening.

This is a particularly bitter pill to swallow for Ukraine, since it was once home to the world’s third-largest cache of nuclear weapons. After the collapse of the Soviet Union, Ukraine inherited a significant slice of the Kremlin’s nuclear arsenal. But in 1994, the newly independent country decided to surrender that arsenal in exchange for assurances from Russia, the United Kingdom, and the United States that its sovereignty and territorial integrity would be respected. The agreement, known as the Budapest Memorandum, is one that many Ukrainians have come to regret—first in the wake of Russia’s 2014 annexation of Crimea and invasion of eastern Ukraine, and now even more so after its all-out assault on the country. If Ukraine had held on to its arsenal, many have argued, Putin would never have dared to invade the country.

America Has No Good Options on Iran

| Jan. 17, 2022

The hard truth is that the United States now has few good options for containing Iran’s nuclear program. It can persist with the no-deal status quo, allowing Iran to continue inching closer to a bomb while suffering under sanctions. It can pursue a return to the 2015 agreement and then attempt to get Iran to agree to a “longer and stronger” pact, as the Biden team has suggested. It can try for various other deals, either more or less stringent than the 2015 agreement. Or it can attempt to destroy Iran’s nuclear infrastructure with a military strike, possibly setting Tehran’s progress toward a bomb back by a few years but almost certainly provoking retaliation and possibly a sprint toward the nuclear finish line.

Durable Institution Under Fire? The NPT Confronts Emerging Multipolarity

The regime built around the 1970 Treaty on the Non-Proliferation of Nuclear Weapons (NPT) has helped curtail the spread of nuclear arms for fifty years. In hindsight, it is remarkable only nine states possess the world’s most powerful weapon. The NPT achieved much success during Cold War bipolarity and U.S. unipolarity in its aftermath. But today, China’s rise and Russia’s resurgence have ushered in a new era of emerging multipolarity. Can the treaty withstand the potential challenges of this dynamic environment? There is a real risk that multipolarity may shake the scaffolding of the nonproliferation regime, presenting a significant test to the NPT’s durability. This article identifies four essential elements of the nonproliferation regime: widespread membership, adaptability, enforcement, and fairness. History suggests bipolarity and unipolarity in the international system largely sustained and promoted these NPT features. When international regimes lack such elements, it sharply curtails their long-term efficacy.

Backchannel Non-Proliferation: Militarily Non-Aligned States and Nuclear Diplomacy

| July 27, 2021

What roles can small militarily non-aligned States play in nuclear non-proliferation diplomacy with actual or suspected proliferators? And how might international law shape such contributions? Current literature identifying effective approaches to nuclear non-proliferation and rollback is somewhat one-dimensional, emphasising the behaviour of great powers and international organisations. By contrast, this chapter analyses activities militarily non-aligned States may undertake supporting negotiations in accordance with international legal norms and institutions. More specifically, it explores Swedish and Swiss initiatives in the early 2000s, a period of growing tensions over the Iranian and North Korean nuclear programmes. Drawing upon resources including unpublished elite interviews, the chapter offers new insights into theoretical backchannel non-proliferation mechanisms. It complements existing literature on nuclear proliferation by offering a fuller account of diplomatic negotiations. Ongoing crises suggest many future challenges to the non-proliferation regime will emerge, and militarily non-aligned States may hold one of the few keys to facilitating dialogue. International law can both compel these States to act and provide them with influential—but often-overlooked—non-proliferation roles. Indeed, reconsidering dominant narratives about ‘players’ involved in nuclear diplomacy may provide new avenues for policy-making and theorising aimed at preventing the spread of nuclear weapons.

Biden to Putin in Geneva: There's a New Sheriff in Town.

| June 17, 2021

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.

How to Make the Iranian Nuclear Deal Durable

| Feb. 28, 2021

Abolghasem Bayyenat and Sayed Hossein Mousavian advise the United States and Iran to aim for reaching a modus vivendi that keeps their political conflict within manageable limits. Otherwise, another round of dangerous mutual escalation in the illusory hope of building leverage and extracting more concessions from each other is inevitable.

Reviving the Nuclear Deal Gives the U.S. More Leverage Over Iran

| Feb. 15, 2021

While U.S. sanctions have caused Iran’s economy major challenges and limited Iran’s access to financial resources, they have not succeeded in changing Tehran’s behavior regarding its nuclear program. Indeed, Iran has not offered additional concessions. Instead, it has engaged in its own leverage-building strategy by ramping up its nuclear activities, missile program, and regional activities. Iran is not only closer to having the capacity to build a bomb, but even the political discourse of key officials on whether to cross that threshold has been shifting.
