Today, President Obama officially nominated John Brennan to direct the CIA, since the previous director made a sudden departure (note to prospective Brennan biographers: Watch your step), but the other appointment, of former Nebraska Republican senator Chuck Hagel to be Secretary of Defense, is what got all the attention. Republicans dutifully trooped to the cable cameras to say somberly that they are "troubled" and "concerned" by Hagel's nomination. Though Hagel was once their esteemed colleague, he made them very angry by turning against the Iraq War after having voted for it in the first place. Because, as they will tell you, the war went swimmingly, and anyone who fails to understand that may not have the judgment to lead the Pentagon.
