Wishful thinking, at best.
Nobody walked into Pakistan and laid down the law to Musharraf and told him to hand over his nukes. After 9-11, our relationship was so tenuous, that we were lucky to get permission just to cross Pakistani territory in order to enter and attack Afghanistan. Musharraf wouldn't have dared do what you suggest for several reasons.
Pakistan is a major hotbed of Islamist radicals that extends all the way up to the highest levels of Musharraf's own military officer corps and intelligence service. It was these organizations that were largely responsible for the Taliban coming to power in Afghanistan, in the first place. This was the reality Musharraf faced when he took over the government in 1999.
Over the intervening 2-1/2 years since 9-11, Musharraf, with clandestine help from the U.S., has made such great progress in arresting al Qa'ida terrorists and ridding his military and intelligence services of the Islamists radicals that last September, Ayman al-Zawahiri, al Qa'ida's second in command, issued a fatwa calling for Musharraf's assassination. They were nearly successful with two attempts made in December. Musharraf needs the U.S. now, since many of the terrorists we chased out of Afghanistan have infested his own country and with the Islamists radicals that riddle his government, he knows he's got a tiger by the tail and we were the only country strong enough and willing to come to his aid.
This whole Pakistani operation to rid that country of terrorists and Islamist radical control, depended on the U.S. getting some measure of control over the Pakistani nuclear stockpile. Such control has been our fall-back plan in case the Islamist/terrorist elements were ultimately successful in overthrowing or assassinating Musharraf.
That control over the nukes damn sure didn't come easily or by simple demand of the U.S. The relationship the U.S. currently has with Musharraf and Pakistan is the product of months and even years of delicate political, diplomatic and intelligence, back-channel efforts (and a few black ops).
This article is good and welcome news.
