Nuclear Issues

Belfer Center Director Graham Allison testified before the U.S. Senate Committee on Foreign Relations on "Lessons Learned from Past WMD Negotiations" to inform assessment of a comprehensive nuclear deal that will prevent Iran from acquiring nuclear weapons.

While the United States and Russia have a responsibility to draw down their arsenals, these bilateral nuclear reductions will be increasingly difficult if other nuclear powers do not join in....[I]t is time to engage the so-called "second tier" nuclear powers, especially China. The evolution of the US-China strategic relationship can affect the next stages of international arms control, even if China does not directly participate.

"Some form of negotiated agreement, if it can be achieved, is the “least bad” option for U.S. interests—but is likely to have to include some continuing enrichment in Iran. There are real security risks in agreeing to permit some ongoing enrichment in Iran, but if appropriately managed, these security risks are less than those created by a military strike or allowing Iran to continue unfettered enrichment with no agreement."
