“It all came from the fact that bin Laden had been hiding in Abbottabad. That was a big shock to us and a big shock to a lot of Americans, because obviously the Pakistanis must have known. There are no two ways about it. Kayani (head of the Pakistani army) must have known, and the ISI must have known. My view is that the Americans now have to be very tough with the Pakistanis and say, 'This is just not good enough, we’re not going to accept this.’”
