Blair unveils proposals for new nuclear arsenal

Britain's Tony Blair launched plans for a multibillion dollar nuclear missile defense system Monday, warning lawmakers the future would likely hold hazardous threats from rogue regimes and state-sponsored terrorists. Blair told Britain's House of Commons the end of the Cold War had brought no guarantees a new "major nuclear threat" would be curbed, citing the weapons ambitions of North Korea and Iran as proof of the enduring need for a defense system. "In these circumstances, it would be unwise and dangerous for Britain alone of any of the nuclear powers to give up its independent nuclear deterrent," the British prime minister said.
