Well, Obama's made things a bit worse when it comes to civil liberties and increasing legal powers of the US Government in the slow decent into a police state that the US has been sliding toward for a few decades. He hasn't vastly made things worse in this regard, just continued the trend established in previous administrations. There's a bunch of controversy surrounding his use of drones on the battlefield, but that's not an issue I've looked at, and frankly don't care all that much about. War is always hell, and civilians always die in war. When you're fighting a war like this, where it's hard to tell the allies, combatants, and non-combatants apart, there's always a high degree of unfortunate civilian deaths. I'm not sure that it's worse than it would be if it was our soldiers out there pulling the triggers, or the drones. I don't have a horse in that race... it's hard to focus on what we're doing over in Afghanistan and Pakistan when things are this bad at home, and threatening to get a lot worse if we elect Romneybot 2000.
But besides the issues above, I feel that Obama's either holding the line, or improving things. I think he's doing more good than ill in this country and in the world. The civil liberties issues we can address later, and will need to. The problem in Afghanistan... well, that was a clusterfuck from the very start since we didn't have the manpower to go in there and do a proper job, since Bush the Lessor decided to lie to the American people and start a second unnecessarily war in Iraq that sapped our manpower, munitions, will, public and international support, and so forth. There really isn't anything more we can do in Afghanistan and Pakistan beside one of these two options: pull out, or institute the draft, raise our troop numbers by hundreds of thousands, and do a full scale invasion of Afghanistan and Pakistan, and hope that the action doesn't pull the Chinese and/or Russians into the war fighting against us. So, we're kinda screwed on there, but Obama's pulling out, so hopefully things will start getting worse over there on that count.
