The U.S. military retreated from Afghanistan two years ago, leaving behind weapons that are now turning up in far-flung trouble spots. In markets that have sprung up across the southern and eastern badlands ... merchants with Taliban permits are offering U.S.-made automatic assault rifles and handguns for sale. Ad hoc weapons bazaars are offering rockets and bombs, shoulder-fired grenade launchers, night vision goggles, sniper rifles and scopes, and ammunition. The Taliban, allies of if not quite affiliates of al Qaeda ... appear to be funneling small arms to like-minded extremists. U.S. assault weapons have reportedly been used in recent attacks by non-state groups in Kashmir, bitterly divided between India and Pakistan, and in Israel's Gaza Strip. The U.S. Department of Defense estimated that left-behind stockpiles of arms and vehicles were worth $7.12 billion of the $18.6 billion spent from 2002 on arming the Afghan security forces. "This included roughly 600,000 weapons of all calibers, nearly 300 fixed-wing and rotary-wing aircraft, over 80,000 vehicles of several models, communications equipment, and other advanced materiel such as night vision goggles and biometric systems," according to the U.S. Special Inspector General for Afghanistan Reconstruction (SIGAR). SIGAR quoted a Taliban official as saying, "The group took possession of more than 300,000 light arms, 26,000 heavy weapons, and about 61,000 military vehicles."
