How much access has Pakistan given to US?

NEW YORK – Pakistan has denied having any understanding with US that would allow specially trained American units to provide added security for the Pakistani nuclear arsenal in case of a crisis, saying it was capable of dealing with any untoward situation.
“Pakistan neither needs any American unit for enhancing the security for its arsenal nor would accept it,” a Pakistani military spokesman was quoted as saying in the course of an in-depth article by investigative journalist Seymour Hersh, who spoke about US efforts to forge a nuclear security deal.
Writing in the latest issue of The New Yorker magazine, Hersh, citing unnamed American and Pakistani officials as saying that the US had been negotiating highly sensitive understandings with the Pak military about the security of Pak nuclear weapons.
Apart from the Pak military’s denial, a spokesman for Admiral Michel Mullen, Chairman of the US Joint Chiefs of Staff, said, “To my knowledge, we have no military units, special forces or otherwise, involved in such an assignment.”
In return for its nuclear weapons’ protection, the Pakistani military would be given money to equip and train its soldiers and to improve their housing and facilities, Hersh wrote.
The principal fear was that extremists inside the Pakistani military might stage a coup, take control of some nuclear assets, or even divert a warhead, the American journalist notes.
“We give comfort to each other, and the comfort level is good, because everybody respects everybody’s integrity,” Hersh quoted President Asif Zardari as telling him in an interview about the security relationship with Washington.
“Our Army officers are not crazy, like the Taliban,” Zardari went on to say. “A mutiny would never happen in Pakistan. It’s a fear being spread by the few who seek to scare the many.”
Meanwhile, former President Musharraf acknowledged that his govt had given US State Department non-proliferation experts insight into the command and control of the Pakistani arsenal and its on-site safety and security procedures, the report said.
