Mchrystal firing and the futile Afghan War

Ok Big Stan is gone, does it make a difference?

From the Michael Hastings article in Rolling Stone

"But even if he somehow manages to succeed, after years of bloody fighting with Afghan kids who pose no threat to the U.S. homeland, the war will do little to shut down Al Qaeda, which has shifted its operations to Pakistan. Dispatching 150,000 troops to build new schools, roads, mosques and water-treatment facilities around Kandahar is like trying to stop the drug war in Mexico by occupying Arkansas and building Baptist churches in Little Rock."

The USA has lost the War. When will they admit this?
