I disagree that Obama promised an increase.
I recall him promising the Left that he was going to pull out of Afghanistan by 2014. http://www.politifact.com/truth-o-meter/promises/obameter/promise/1096/end-war-afghanistan-2014/
So no, I wasn't expecting him to increase forces in Afghanistan. And he has completely broken that promise. Not the first promise he's broken, clearly.
Either way, Obama has put himself into a terrible situation and has made things much worse than when Bush left office. Now Afghanistan is really seeming to descend into tumult and divert our attention away from Iraq - which is spiraling out of control and could pose a serious danger to US security in the region.
