That would be the Obama who opposed George W. Bush's aggressive interpretation of presidential war powers. "The president does not have power under the Constitution to unilaterally authorize a military attack in a situation that does not involve stopping an actual or imminent threat to the nation," Obama said in 2007.
But once in the White House, Obama suddenly grasped the attractions of being free to do whatever you want without getting permission from fussbudgets on Capitol Hill. He intervened in the 2011 Libya civil war while claiming the action was exempt from the time limits in the 1973 War Powers Resolution. His refusal reached unprecedented heights of absurdity when the administration insisted that sending U.S. planes and missiles to destroy enemy targets did not trigger the law because it did not constitute "hostilities."
Obama never admitted second thoughts about how he handled Libya. And in recent days, he gave every indication that he planned to act with similar disregard for the law and the Constitution in Syria.
Facing requests that he put the question to Congress, the White House released a statement Thursday saying, "The views of Congress are important to the president's decision-making process." It sounded exactly like that recording when you're on hold that says, "Your call is very important to us." He bridled at the idea that the lawmakers were entitled to anything more than an explanation of what he planned to do without their consent.
But in the end, he had the grace and maturity of judgment to change course. Maybe he was persuaded by the letter, signed by 140 House members, that could have been taken from his 2008 position papers. "Engaging our military in Syria when no direct threat to the United States exists and without prior congressional authorization," the letter said, "would violate the separation of powers that is clearly delineated in the Constitution."
Maybe he was sobered by the sight of the British Parliament standing up on its hind legs and rejecting Prime Minister David Cameron's plan to join the attack against the forces of President Bashar al-Assad. Maybe he reviewed lecture notes from his time teaching constitutional law and realized how grossly out of step he was with the intent of the framers and the mandates of the law.
