The Telegraph has a reasoned editorial:

Americans know instinctively that once soldiers' lives are at risk on the orders of their commander-in-chief, the President, the debate must stop. They understand that, as that enduring old saw goes, politics stops at the water's edge.

Many in Britain like to mock the excessive manifestations of American patriotism. But how our soldiers in southern Iraq must envy their American counterparts in their knowledge of unquestioned support back home. In its desire to be seen to be backing the troops, the American heartland is not lapsing into anti-Muslim bloodlust. The emphasis at the patriotic rallies is much more on getting the job done than kicking Saddam's butt.

Most Americans at least.
