Was Pakistan ever a friend? How many $billions haves been sent to Pakistan as gift, courtesy of US taxpayers? Sans that Pakistan would not even pretend to be a friend.
Pakistan was extremely useful for us during the initial attacks on Al Qeda/Taliban. It took a lot of skill to do this.
Pakistan is a mess, and dangerous. Using them for our purposes is the best scenario. Obama is blowing this and making a dangerous situation much worse.
Nope. But Bush did some serious arm-twisting to ensure they would not actively interfere with our troops/efforts in Afghanistan. While it has been an uneasy "truce", Obama started washing away the sands of the foundations during his first campaign - he's just finishing the job now.
