This is not the Barack Obama I thought I knew

Throughout his presidential campaign, Mr. Obama excoriated Mr. Bush’s counterinsurgency strategy in Iraq, insisting it could not succeed. Earlier this year, facing increasing violence in Afghanistan, Mr. Obama rejected warnings of a “quagmire” and ordered more troops to that country. He isn’t calling it a “surge” but that’s what it is. He is applying in Afghanistan the counterinsurgency strategy Mr. Bush used in Iraq.

As a candidate, Mr. Obama promised to end the Iraq war by withdrawing all troops by March 2009. As president, he set a slower pace of drawdown. He has also said he will leave as many as 50,000 Americans troops there.

These reversals are both praiseworthy and evidence that, when it comes to national security, being briefed on terror threats as president is a lot different than placating MoveOn.org and Code Pink activists as a candidate. The realities of governing trump the realities of campaigning.
