A “Nuclear Umbrella” for Ukraine? Precedents and Possibilities for Postwar European Security

| Winter 2023/24

Europe after the Russo-Ukrainian War must develop a new security structure to defend against any Russian aggression. The safest option is a non-offensive, confidence-building defense. This option includes proposals such as the “spider in the web” strategy and the “porcupine” strategy to provide for European security in a region threatened by Russian expansion—without relying on the threat of nuclear war.

Defending the United States: Revisiting National Missile Defense against North Korea

| Winter 2021/22

The costly Ground-based Midcourse Defense system remains unproven and unreliable in deterring North Korea’s threat to use intercontinental ballistic missiles. An airborne boost-phase intercept system may offer an alternative defense against North Korea without threatening Russian or Chinese deterrents.

A Financial Sanctions Dilemma

| Winter 2020

Over the last two decades, there has been a dramatic increase in the popularity of financial sanctions as an instrument of US foreign policy to address security threats ranging from weapons of mass destruction (WMD) proliferation and terrorism to human rights violations and transnational crime. Washington’s policymakers have prized these tools for their ability to rapidly apply pressure against foreign targets with few perceived repercussions against American business interests. The problem, however, is that Washington is ignoring a growing tension between financial sanctions designed to support economic statecraft (with non-financial goals) and those designed to protect the international financial system. Confusing the two sends mixed signals to adversaries as well as allies and undermines US credibility and commitment to upholding international banking rules and norms. If Washington cannot reconcile these competing processes, it is unlikely that future administrations will enjoy the same foreign policy levers, leaving the United States at a significant disadvantage.

Dangerous Confidence? Chinese Views on Nuclear Escalation

    Authors:
  • Fiona S. Cunningham

| Fall 2019

China and the United States hold opposing beliefs about whether nuclear war can be avoided in a potential crisis or armed conflict. Taken together, these opposing beliefs increase the risk of nuclear escalation and can lead to greater crisis instability.

The President's Speech: Choosing Between Mom and Dad

| August 6, 2015

"..."[I]t is time for the Prime Minister to come to his senses and to understand that a small country, whose very existence depends today on the United States, cannot physically block a major presidential initiative. Instead, he would be wise to work with the American administration to close gaps in the agreement, maintain close intelligence supervision of Iran's observance of the agreement, and even to take advantage of this moment to try and reach an historic defense treaty with the United States."

Strategies of Inhibition: U.S. Grand Strategy, the Nuclear Revolution, and Nonproliferation

| Summer 2015

Most histories of post-1945 U.S. grand strategy focus on containment of the Soviet Union and U.S. efforts to promote political and economic liberalization. A closer look reveals that "strategies of inhibition"—attempts to control nuclear proliferation—have been a third central pillar of U.S. grand strategy for several decades.

Alliance Coercion and Nuclear Restraint: How the United States Thwarted West Germany's Nuclear Ambitions

| Spring 2015

A prominent model of nuclear proliferation posits that a powerful patron state can prevent a weaker ally from proliferating by providing it with security guarantees. The history of West Germany's pursuit of the bomb from 1954 to 1969 suggests that a patron may also need to threaten the client state with military abandonment to convince it not to acquire nuclear weapons.
