WASHINGTON — The Obama administration is increasingly emphasizing the idea that the United States will have forces in Afghanistan until at least the end of 2014, a change in tone aimed at persuading the Afghans and the Taliban that there will be no significant American troop withdrawals next summer.

In a move away from President Obama’s deadline of July 2011 for the start of an American drawdown from Afghanistan, Defense Secretary Robert M. Gates, Secretary of State Hillary Rodham Clinton and Adm. Mike Mullen, the chairman of the Joint Chiefs of Staff, all cited 2014 this week as the key date for handing over the defense of Afghanistan to the Afghans themselves. Implicit in their message, delivered at a security and diplomatic conference in Australia, was that the United States would be fighting the Taliban in Afghanistan for at least four more years.

A deadline that keeps slipping; U.S. supporting a corrupt government because "What's the alternative?"; an intractable enemy operating and supported from a neighboring country; and more dead and maimed soldiers. Sounds a lot like Vietnam. All we need is Pete Seeger to complete the picture.
