Obama doesn't want to win the wars, but he really doesn't want to be blamed for losing them. So he puts on a show of continuing to support the war efforts, even to include risking more servicemen, but he's not in it to win it. He delays, he dithers, he projects weakness, he denies the military what they need to do a proper job. But he looks like he's trying, so he gets exactly what he wants. War is lost, he isn't blamed.
