Wired.com and DNAIndia.com report a chilling reaction to the Pakistani military's fear that the United States will seek to neutralize or steal their nukes. So instead of storing their nuclear weapons in carefully guarded bunkers, they have seen fit to hide them in nondescript vans that move around frequently.
"The irony is that the U.S. isn’t planning to steal Pakistan’s nukes — but Pakistan’s cavalier attitude toward nuclear security is making the U.S. think twice about whether it should revise some worst-case-scenario contingency planning...."
UPDATE: It was bound to happen sooner or later. According to AFP/Google, the Pakistani government angrily denied resorting to such an unsecure method of dispersing their nuclear weapons.
