Well lets see. Bush 1 started a war he had not intention of letting the soldiers win, or finish, while protecting an oil thief, from another just as bad as the oil thief. Bush 2, escalated that war, still with the intention of never actually letting the soldiers win, and started yet another war, where bombing would have sufficed, and which he had neither the intention or stomach, to win, and also shows no signs of being over.
So while Obama pours our money and "imagined status" in the world, out on the ground, both Bushes poured our "blood", and our money, and "imagined status" on the ground.
You'll have to go back farther than Reagan to find a truly good President.
