Russia’s nuclear forces are expected to drop well below 500 offensive strategic delivery vehicles within the next five years, less than one-third of what’s permitted by the 1991 START treaty.

I was in good company with Ambassador Linton Brooks, the former U.S. chief negotiator on the START treaty, who spoke about the key issues and challenges the START follow-on negotiators will face, and Greg Thielmann, formerly senior professional staffer of the Senate Select Committee on Intelligence, who discussed how the a new agreement might be verified through START-style verification tools.

The report is the latest in a serious of revelations over the past four years about China’s growing nuclear weapons arsenal and the deepening […]
