His credibility on national security and standing up against the terrorists makes him right up there with Harry Truman dropping the bombs on Japan.
As POTUS, Truman was a failure and resigned from running for reelection. His legacy was resurrected by liberal historians and the liberal media. The same liberal establishment that still ranks both JFK and Clinton as great Presidents.
Bush should get some kudos from history for taking the fight to the enemy. But I seriously doubt there is enough success for historians to ever rank Bush much above the level of average. A good man and a decent POTUS.
