Which is why Obama is consciously creating a gulf between what he now dismissively calls "campaign rhetoric" and the policy choices he must now make as president. Accordingly, Newsweek -- Obama acolyte and scourge of everything Bush/Cheney -- has on the eve of the Democratic restoration miraculously discovered the arguments for warrantless wiretaps, enhanced interrogation and detention without trial. Indeed, Newsweek's neck-snapping cover declares, "Why Obama May Soon Find Virtue in Cheney's Vision of Power."
Obama will be loath to throw away the tools that have kept the homeland safe. Just as he will be loath to jeopardize the remarkable turnaround in American fortunes in Iraq.
Obama opposed the war. But the war is all but over. What remains is an Iraq turned from aggressive, hostile power in the heart of the Middle East to an emerging democracy openly allied with the United States. No president would want to be responsible for undoing that success.
In Iraq, Bush rightly took criticism for all that went wrong -- the WMD fiasco, Abu Ghraib, the descent into bloody chaos in 2005-06. Then Bush goes to Baghdad to ratify the ultimate post-surge success of that troubled campaign -- the signing of a strategic partnership between the U.S. and Iraq -- and ends up dodging two size-10 shoes for his pains.
Absorbing that insult was Bush's final service on Iraq. Whatever venom the war generated is concentrated on Bush himself. By having personalized the responsibility for the awfulness of the war, Bush has done his successor a favor. Obama enters office with a strategic success on his hands -- while Bush leaves the scene taking a shoe for his country.
Which is why I suspect Bush showed such equanimity during a private farewell interview at the White House a few weeks ago. He leaves behind the sinews of war, for the creation of which he has been so vilified but which will serve his successor -- and his country -- well over the coming years. The very continuation by Democrats of Bush's policies will be grudging, if silent, acknowledgement of how much he got right.
