Past American governments have used sabre-rattling as a useful tactic to get some bad actor on the world stage to fall in line. This government hasn’t mastered that kind of subtlety. When Dick Cheney has rattled his sabre, it has generally meant that he intends to use it. And in spite of recent war spasms aimed at Iran from this sclerotic administration, Fallon is in no hurry to pick up any campaign medals for Iran. And therein lies the rub for the hard-liners led by Cheney. Army General David Petraeus, commanding America’s forces in Iraq, may say, “You cannot win in Iraq solely in Iraq,” but Fox Fallon is Petraeus’s boss, and he is the commander of United States Central Command, and Fallon doesn’t extend Petraeus’s logic to mean war against Iran.

So while Admiral Fallon’s boss, President George W. Bush, regularly trash-talks his way to World War III and his administration casually casts Iranian president Mahmoud Ahmadinejad as this century’s Hitler (a crown it has awarded once before, to deadly effect), it’s left to Fallon — and apparently Fallon alone — to argue that, as he told Al Jazeera last fall: “This constant drumbeat of conflict is not helpful and not useful. I expect that there will be no war, and that is what we ought to be working for. We ought to try to do our utmost to create different conditions.”

What America needs, Fallon says, is a “combination of strength and willingness to engage.”

Those are fighting words to your average neocon — not to mention your average supporter of Israel, a good many of whom in Washington seem never to have served a minute in uniform. But utter those words for print and you can easily find yourself defending your indifference to “nuclear holocaust.”

How does Fallon get away with so brazenly challenging his commander in chief?

The answer is that he might not get away with it for much longer. President Bush is not accustomed to a subordinate who speaks his mind as freely as Fallon does, and the president may have had enough.
