North Korea 'may have only one nuke'

North Korea may have only a single nuclear weapon and there is no proof that the reclusive country has actually produced any, the head of the international consortium set up to replace North Korea’s plutonium-producing reactors said.

Figures up to a half-dozen and sometimes more are circulated in discussions of North Korea’s self-proclaimed program. South Korean Deputy Foreign Minister Lee Soo-hyuck said in April that North Korea could make eight bombs by reprocessing 8,000 spent nuclear fuel rods.
