Kevin McGehee has posts over at blogoSFERICS and Flyover Blogdom Today (link via Instapundit) in part discussing his hypothesis that US threats to wipe out Pakistani nukes was the key contributer to Pakistani support in Afghanistan. He may be right, and, related to my earlier suggestion below, similar US threats or actions may help prevent a nuclear exchange. I hope so, but I am unsure that we have the assets in place to make good on any threats.
