<br/>The US and Russia, countries with the largest nuclear stockpiles, have reached an agreement to considerably reduce their atomic weapons, in a landmark deal that could "reset" relations between the former Cold War rivals.<br/><br/> The White House announced that the agreement reached between US President Barack Obama and his Russian counterpart Demetry Medvedev envisages a 30 per cent reduction in nuclear stockpile and will be signed by the two leaders in Prague on 8th April. .<br/><br/> This landmark agreement advances the security of both nations, and reaffirms American and Russian leadership on behalf of nuclear security and global non-proliferation. <br/><br/> The new Treaty will contain limits on US and Russian<br/><br/>nuclear forces significantly below the levels established by<br/><br/>the START treaty signed in 1991, and the Moscow Treaty signed in 2002.<br/><br/> The new START Treaty will specify limits of 1,550<br/><br/>deployed warheads, which is about 30 per cent lower than the upper warhead limit of the Moscow Treaty; 800 deployed and non-deployed intercontinental ballistic missile (ICBM) launchers, submarine launched ballistic missile (SLBM) launchers, and heavy bombers equipped for nuclear weapons; and 700 for deployed ICBMs, SLBMs, and heavy bombers equipped for nuclear weapons.
