Who do you want answering that phone at 3 a.m.? A man who’s been cramming on these issues for the last year, who’s never had to make an executive decision affecting so much as a city, let alone the world? A foreign-policy novice instinctively inclined to the flabbiest, most vaporous multilateralism (e.g., the Berlin Wall came down because of “a world that stands as one”), and who refers to the most deliberate act of war since Pearl Harbor as “the tragedy of 9/11,” a term more appropriate for a bus accident?

A man who not only has the best instincts, but has the honor and the courage to, yes, put country first, as when he carried the lonely fight for the surge that turned Iraq from catastrophic defeat into achievable strategic victory?
