START negotiated the largest and most complex arms control treaty in history, and its final implementation in late 2001 resulted in the removal of about 80% of all strategic nuclear weapons then in existence. Proposed by US President Ronald Reagan, it was renamed START I after negotiations began on START II.
The treaty expired on 5 December 2009.
On 8 April 2010, the replacement New START Treaty was signed in Prague by US President Barack Obama and Russian President Dmitry Medvedev. Following its ratification by the US Senate and the Federal Assembly of Russia, the treaty went into force on 26 January 2011, extending deep reductions of American and Soviet or Russian strategic nuclear weapons through February 2026.
