UNRELIABLE AFGHAN ALLIES

"... Four U.S. Marines were killed... assigned as trainers to the Afghan National Army... and the Marine commander's Afghan interpreter also died in the ambush and the subsequent battle... U.S. officers said they suspected that the insurgents had been tipped off by sympathizers in the local Afghan security forces or by the village elders... "Whatever we do always leaks,. You can't trust even some of their soldiers or officers."
