Talking about GW's SOTU speech, Fred Kaplan brings up a very good point:

What is most head-shaking of all is that, after four years of this war, the president once more fell short of making its case. As in the past, he said that it's very important—"a decisive ideological struggle," he called it, adding, "nothing is more important at this moment in our history than for America to succeed." And yet he also said that America's commitment to the war is "not open-ended." How can both claims be true? If nothing is more important, it must be open-ended. If it's not open-ended, it can't be all that important.

Bingo -- but it's not the first time GW has said something that makes little sense once you probe it a bit.
