Russia voices concern over new US nuclear weapon

A senior Russian diplomat raised concern Wednesday about the United States deploying a new submarine-launched nuclear weapon, saying the move signaled Washington's belief that it could wage a limited nuclear conflict. The Pentagon's top policy official told The Associated Press this week that a a nuclear warhead of reduced destructive power had been fitted onto a Trident II intercontinental ballistic missiles carried by nuclear submarines. John Rood, the undersecretary of defense for policy, said the deployment of the so-called low-yield warheads lowers the risk of nuclear war by helping dissuade Russia from initiating a limited nuclear conflict.
