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.

With this in mind, Russia is MIRVing its ballistic missile to keep some level of parity with the United States.
This and more from a briefing I gave this morning at the Arms Control Association meeting Next Steps in U.S.-Russian Nuclear Arms Reductions. 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.
