Last night, he answered: "Saying 'bring it on,' kind of tough talk, you know, that sent the wrong signal to people. I learned some lessons about expressing myself maybe in a little more sophisticated manner -- you know, 'wanted dead or alive,' that kind of talk. I think in certain parts of the world it was misinterpreted, and so I learned from that."
In other words, Bush has regrets purely about how his language was "misinterpreted", not about in how it was properly and accurately understood, as the language of a chickenhawk, the language of someone who is in no danger. It's all very fine and well to talk like a tough guy when the shells are exploding around you and your ship seems to be on the verge of sinking. That's heroic and that deserves respect. Talking like a tough guy from halfway around the world is the action of a coward and deserves nothing but scorn.
The blog Crooks & Liars has a marvelous picture of Bush that beautifully sums up how our President feels about the whole press conference.
Excellent post from DailyKos on chickenhawks and on who really deserves to be honored on Memorial Day.
