Happily for Mr Zarqawi, no matter how desperate the head-hackers get, the Western defeatists can always top them. A Democrat Congressman, Jack Murtha, has called for immediate US withdrawal from Iraq. He's a Vietnam veteran, so naturally the media are insisting that his views warrant special deference, military experience in a war America lost being the only military experience the Democrats and the press value these days. Hence, the demand for the President to come up with an "exit strategy".

In war, there are usually only two exit strategies: victory or defeat. The latter's easier. Just say, whoa, we're the world's pre-eminent power but we can't handle an unprecedently low level of casualties, so if you don't mind we'd just as soon get off at the next stop.

Demonstrating the will to lose as clearly as America did in Vietnam wasn't such a smart move, but since the media can't seem to get beyond this ancient jungle war it may be worth underlining the principal difference: Osama is not Ho Chi Minh, and al-Qa'eda are not the Viet Cong. If you exit, they'll follow. And Americans will die - in foreign embassies, barracks, warships, as they did through the Nineties, and eventually on the streets of US cities, too.
