Parsing Bush's new mantra.

President Bush's national security adviser, Stephen Hadley, said today that the arguments over how and why the war began are irrelevant. "We need to put this debate behind us," he said. But the truth is, no debate could be more relevant now. As the war in Iraq enters yet another crucial phase—with elections scheduled next month and Congress finally taking up the issue of whether to send more troops or start pulling them out—we need to know whether the people running the executive branch can be trusted, and the sad truth is that they cannot be.
