I hope thats sarcasm, because he is doing the opposite of everything he said he'd do, like just for like instance; getting the US troops the hell out of Afghanistan etc..
Getting the troops out of Afghanistan requires removing the Taliban/Al-Qaida influence from the Afghani provinces as much as possible, which the military cannot do without the 20-some thousand extra troops that military leaders there had been calling out for for over three years. Now that the Iraq War is on a downswing, forces can be redistributed to focus on Afghanistan, for the purposes of stabilizing the region, allowing us to withdraw troops starting in 2011.
That's the only strategy he's had since he was President. He is not "doing the opposite." He may not be doing it in the manner you expect, but he's doing exactly what he said he'd do.
