No one said Bush gets the credit.
He needs to focus on the FACTS of his foreign policy, not just deflect onto things that other agencies have been handling for 2 administrations. Obama's foreign policy is supposed to be his stand on how we interact/deal with other countries, not that he gave the ok for Ops to kill men that have been being hunted by American Agencies for years before he came into office.
Yes things change, but he did not change shit as far as the FBI, CIA, and Military manhunts for those high value targets, he let them do their job, and then said "ok" when they asked permission to take out said high value targets. He didnt tell them what to do, he didnt set them on their path, he didnt do shit that led to the aquiring and termination of said targets. Neither he nor Bush should get credit, the agencies should.
And he sure as shit shouldnt try and pawn it off as his stand on foreign policy, when it has NOTHING to do with it.
