What can the United States do to thwart the nuclear ambitions of its allies? Dr. Kogan analyzes past cases where the United States was able to leverage its alliance commitments to stop friendly states from going nuclear. He then asks what lessons these past nuclear negotiations hold for today. In the coming decade, key U.S. allies in the Middle East (Saudi Arabia) and East Asia (South Korea, Japan) may consider reducing their reliance on U.S. security guarantees by acquiring independent nuclear deterrents. In conversation with Project Director Kevin Ryan, Dr. Kogan discusses Washington's options in confronting these contemporary allies with nascent nuclear appetites.
