Sure, John McCain, let's just keep doing the same thing...maybe if we keep doing it you can wipe out an entire generation -- of Americans

On the eve of John McCain's "Failure is not an option" tour, the Bush Administration policy he's determined to continue has turned American troops into sitting ducks:

The renegade cleric Muqtada al-Sadr urged the Iraqi army and police to stop cooperating with the United States and told his guerrilla fighters to concentrate on pushing American forces out of the country, according to a statement issued Sunday.

The statement, stamped with al-Sadr's official seal, was distributed in the Shiite holy city of Najaf on Sunday — a day before a large demonstration there, called for by al-Sadr, to mark the fourth anniversary of the fall of Baghdad.

"You, the Iraqi army and police forces, don't walk alongside the occupiers, because they are your archenemy," the statement said. Its authenticity could not be verified.

In the statement, al-Sadr — who commands an enormous following among Iraq's majority Shiites and has close allies in the Shiite-dominated government — also encouraged his followers to attack only American forces, not fellow Iraqis.

"God has ordered you to be patient in front of your enemy, and unify your efforts against them — not against the sons of Iraq," the statement said, in an apparent reference to clashes between al-Sadr's Mahdi Army fighters and Iraqi troops in Diwaniyah, south of Baghdad. "You have to protect and build Iraq."

The U.S. military on Sunday announced the deaths of four American soldiers, killed a day earlier in an explosion near their vehicle in Diyala province northeast of Baghdad. The province has seen a spike in attacks on U.S. and Iraqi forces since the start of a plan two months ago to pacify the capital. Officials believe militants have streamed out of Baghdad to invigorate the insurgency in areas just outside the city.

Sure, John, let's keep doing what we're doing. After all, doesn't whack-a-mole always work?

Meanwhile, the "temporary surge" is looking more and more like a permanent occupation:

Defense Secretary Robert M. Gates said Thursday that it was unclear how long the current buildup of U.S. forces in Baghdad would last and that commanders would have to wait until midsummer to evaluate whether it was working.

Gates has said he hopes to end the deployment of 21,500 additional combat troops and thousands of support personnel by December. But in recent weeks, some senior officers, including the Army general in charge of day-to-day operations in Iraq, have suggested that the so-called surge may have to be extended into early next year. The recommendation is being debated by senior commanders.

At a Pentagon news conference, Gates did not directly address a suggestion by Lt. Gen. Raymond T. Odierno, the operations commander, to maintain the higher troop levels. He said any decisions on troop numbers would depend on progress on the ground.

"The truth is, I think people don't know right now how long this will last," Gates said. "The thinking of those involved in the process was that it would be a period of months, not a period of years, or a year and a half or something like that."

Someone had better tell McCain that he can't win the Vietnam War by sending another generation to die for no reason.
