Nuclear Issues

The historical record does not support the idea that nuclear energy programs increase the odds of proliferation.

The constraints imposed on Iran’s activities under the Joint Comprehensive Plan of Action (JCPOA) curb Tehran’s nuclear program for eight to 15 years. The key restrictions on the program, however, disappear over time, leaving Tehran with an industrial-size nuclear program with near-zero nuclear breakout time and an easier, advance-centrifuge-powered clandestine “sneak out” time.

The United States and Russia are the two countries with the vast majority of the world's nuclear weapons and material. In an age of global terrorism, they share both a special responsibility in ensuring that they each employ effective nuclear security systems and an understanding of the unique challenge of securing hundreds of tons of nuclear material. For two decades, the United States and Russia lived up to this responsibility by working together to strengthen nuclear security in Russia and around the globe. That ended in 2014 when Russia halted the majority of its work on nuclear security with the United States. The negative consequences of that decision could seriously affect international security and cooperation in the nuclear realm.

Last fall, experts from around the world gathered to identify ways to strengthen nuclear security cooperation between the United States and Russia and the United States and China. In this Policy Brief, Nickolas Roth summarizes that conversation and provides policy recommendations based on it.

"Recent evidence confirms that the Osirak reactor was intended not to produce plutonium for a weapons program, but rather to develop know-how that would be necessary if Iraq acquired an unsafeguarded reactor better suited for large-scale production of plutonium. Israel's attack triggered a far more focused and determined Iraqi effort to acquire nuclear weapons."

There is no endemic reason for Russian-U.S. relations to be as tense as they have become over the past several years. Th is situation is largely due, on one side, to mishandling of Russian affairs by both the Clinton and Bush administrations, and on the other by the obvious manipulation of anti-Americanism for domestic gain by the Vladimir Putin and Dmitry Medvedev administrations in Russia. Unfortunately, this means that only unilateral U.S. action can undermine the cynical policies of the Russian leadership and restore dynamism to the Russian-U.S. relationship.
