"Dangerous Hypothetical"

The New Republic's Michael Crowley recent wrote the following:

"A DANGEROUS HYPOTHETICAL":

That's what Bush called a question this morning about the possibility that he may impose an Iraq troop surge against the wishes of military leaders. The mere fact that Bush used a loaded word like "dangerous" makes me queasy. When was the last time even the whiff of military insubordination was in the air during wartime? Truman-MacArthur? Seems we're flirting with some uncharted territory--and it's all a bit chilling.

I'm not exactly sure what Crowley is getting at, but I hope he means that the danger is that the military will refuse to follow an order from the President. Bush's plan to increase the number of troops in Iraq may or may not be a good idea, but he's the President and the Commander in Chief. He determines what the military will or will not do, not the other way around.
