START Pact Expires

The Strategic Arms Reduction Treaty (START) between Russia and the U.S., which has been a cornerstone of international nuclear security since 1991, expired on 5 December 2009. The parties failed to sign a replacement treaty by that date, as they repeatedly promised. Both the White House and the Kremlin, however, declared that they were still committed to a new treaty “at the earliest possible date.”
