A Hurting Stalemate? The Risks of Nuclear Weapon Use in the Ukraine Crisis

| Feb. 27, 2022

Nuclear experts are trained to think the unthinkable. So, here is an unthinkable scenario that might actually happen in real life:

The battle over Ukraine drags on. From both the European Union and the United States, fresh weapons and other supplies continue to enter into Ukraine and allow the Ukrainian forces to fight on. The battle reaches what conflict resolution expert William Zartman calls “a hurting stalemate” situation. The balance of forces on the ground is not completely or perfectly symmetrical, but what was once considered a completely disproportioned asymmetry of forces has been gradually re-equilibrated, in favor of the Ukrainian forces.

Ukraine Got A Signed Commitment in 1994 to Ensure its Security – But Can the US and Allies Stop Putin’s Aggression Now?

| Jan. 21, 2022

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?

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.

Will the Nuclear Posture Review Reveal the Biden Doctrine?

| Oct. 12, 2021

In managing expectations across a broad spectrum of stakeholders, the Biden administration should aim to release an NPR grounded in clear-eyed analysis but moderate in tone and posture. It should be guided by what international relations theorists call “defensive realism.” While depicting vividly and without hesitation a world in crisis, the NPR should argue that a return to a classical nuclear deterrence posture is the most effective strategy for the United States.

The CTBT at 25: How Might the International Community Better Foster Its Entry Into Force?

| Sep. 24, 2021

Creating the conditions for the CTBT to enter into force has eluded the international community for the past 25 years. Since the CTBT opened for signature in 1996, the geopolitical landscape has only deteriorated.

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 Sure Neutrons Save Lives Instead of End Them

| May 12, 2021

To ensure that the world has reliable access to the neutrons it needs, at the lowest possible cost, and to facilitate further efforts to minimize and eventually eliminate civilian use of highly enriched uranium, we need an international mechanism to anticipate worldwide neutron needs and plan how to meet them. In essence, the 2016 National Academies’ report recommendation (which sadly remains unfulfilled even in the United States) should be internationalized.

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.
