Obama campaigned on winding down Iraq, which happened, and ramping up Afghanistan, which happened.
On his second day in office, Obama signed an executive order to close Gitmo. Congress outmaneuvered him, bolstered by DINOs and Blue Dogs, and made it illegal to fund any relocation or closure efforts.
Obama has initiated several new military adventures since then, expanding drone attacks throughout Lybia, Pakistan, Yemen, and Somalia. These attacks included the assassinations of American citizens.
Also he was apparently so pissed at failing to get rights for the people at Gitmo that he decided to make their lives worse.
