Obama promised a surge into Afghanistan. He promised an eventual pullout from Iraq, and it looks like he's following through - on Bush's schedule.
Congress shut down Obama's attempts to close Gitmo and forbade him from using any federal funds to do just about anything with it. While I wish he'd tried harder, he did attempt it. I'd be more concerned about the continued NSA wiretapping.
The President is not a dictator. People tend to radically overestimate how much the President can really do.
And yes, the same is true for Bush. Bush couldn't have gone to war without Congress. He couldn't have passed the Patriot Act without Congress. He couldn't have passed No Child Left Behind without Congress. He couldn't have racked up massive deficits without Congress. Heck, even today, virtually our entire deficit (that comes from government policy and not the recession) comes from the Bush tax cuts Congress (including Paul Ryan) passed and the wars.
