Seymour Hersh has written an article in the most recent New Yorker entitled “Why is Washington going easy on Pakistan’s nuclear black marketers?” According to Mr. Hersh, the answer is that the U.S. agreed to let Pakistani President Musharraf pardon a known dealer in nuclear-weapons materials so that President Musharraf would allow the U.S. to operate in a region of Pakistan that would facilitate the capture of Osama bin Laden. As usual with Mr. Hersh’s work, fascinating reading.
