We can't disarm the entire Afghan army. But something has to be done to stop this madness.

CBS News:

Two U.S. troops were shot dead in southern Afghanistan when three assailants, two of whom were believed to be Afghan soldiers, turned their weapons against American troops on Thursday.

Afghan and U.S. military officials confirm to CBS News that the dead were U.S. troops, and that a third American servicemember was wounded in the attack. U.S. forces responded with gunfire and killed the two assailants in Afghan army attire, wounding a third Afghan shooter in civilian clothing. The wounded shooter was identified as a teacher and is in custody.

CBS News correspondent Mandy Clark reports the shooting occurred inside a joint Afghan-U.S. base in Kandahar province.

Thursday's shooting is the latest case of Afghan policemen or soldiers - or militants disguised in their uniforms - killing NATO troops.

Six Americans have now been killed and at least 15 wounded in attacks in Afghanistan since the Islamic holy books were burned at a U.S. base there. Dozens of Afghans have been killed or wounded in riots.

Where is President Karzai? Ultimately, it is his responsibility. And why isn't the president demanding an apology from the Afghan government?

This is insane. Why are we fighting for people who would just as soon kill us? They deserve to live under the jackboot of Taliban authoritarianism. They certainly don't deserve the selfless courage and dedication to duty being exhibited by our troops.
