US SUPPLIED WEAPONS TO TALIBAN IN AFGHANISTAN !

in the early 1980s, the CIA and the ISI (Pakistan's Inter-Services Intelligence agency) provided arms to Afghans resisting the Soviet invasion of Afghanistan, and the ISI assisted the process of gathering radicals from around the world to fight against the Soviets.
Osama Bin Laden was one of the key players in organizing training camps for the foreign volunteers. The U.S. poured funds and arms into Afghanistan, and "by 1987, 65,000 tons of U.S.-made weapons and ammunition a year were entering the war."
FBI translator Sibel Edmonds, who has been fired from the agency for disclosing sensitive information, has claimed United States was on intimate terms with Taliban and Al-Qaeda, using them to further certain goals in Central Asia.

The Taliban were based in the Helmand, Kandahar, and Uruzgan regions and were overwhelmingly ethnic Pashtuns and predominantly Durrani Pashtuns.

According to the Pentagon agency responsible for combating roadside bombs in Iraq and Afghanistan, the increased Taliban threat to US and NATO vehicles comes from Italian-made mines left over from the US Central Intelligence Agency's military assistance to the anti-Soviet jihadists in the 1980s.
