U.S. implementing post-Cold War, preemptive-based nuclear deterrence

The U.S. military has entered into an implementation phase of President George W. Bush's new nuclear doctrine, including preemptive nuclear strikes against "rogue states" that possess weapons of mass destruction such as North Korea and Iran, governmental sources and nuclear specialists told Kyodo News recently.
The U.S. Strategic Command, or STRATCOM, for potential nuclear operations during and after the Cold War set up a new command unit, called the Joint Functional Component Command Space and Global Strike, or JFCCSGS, early in 2005 to accomplish military offensive missions provided by the Nuclear Posture Review, a comprehensive blueprint of nuclear strategy the Defense Department submitted to Congress four years ago.
