Some back-of-the-envelop math on Barack Obama's speech last night. Although he acknowledged that we are "a nation at war," in a speech of 6182 words the president used just 468 of them to talk about national security - the military and diplomacy, together - approximately 7 percent. Of course the speech had to be largely -- even overwhelmingly -- about the economy. But the war was overshadowed by Obama's other priorities, too. He devoted some 827 words to education, 13 percent -- nearly double the time he spent talking about national security. Most extraordinary, as Bill Kristol pointed out below, is his failure to talk about the 17,000 additional soldiers he will be sending to Afghanistan, other than a passing mention of "more who are ready to deploy." Who are they? Why are they being sent? What will they do? What are his goals? We are left to wonder.
