You’re playing word games too. The US never armed the Taliban. Yes, the US armed anti-Soviet fighters in the 80’s and many of those fighter ended up joining the Taliban years later, but to say “the US armed the Taliban” is being dishonest.
They didn't, he's oversimplifying it greatly. The US armed the Mujahadeen throughout the 1980s (through the Pakistani ISI and Pakistani state), leaving behind a vast amount of unused weaponry in Afghanistan. This was during the period prior to the soviet ground forces' withdrawal from Afghanistan and prior to the ending of the Najibullah government, and the killing of Najibullah.
It definitely is a fact that during the 1980s the US pursued a policy of "the enemy of my enemy...", in which the hardcore fundamentalist/sharia law politics and religious ideology of some of the mujahadeen they supported (Bin Laden included), were seen as secondary or tertiary to the primary mission of killing soviet soldiers, and bringing about the end of the soviet-backed government.
Some of the former Muj, predominantly the very fundamentalist Pashtun factions, later became the Taliban which seized Kandahar in 1994, and then Kabul in 1996. At that point the US had not been supporting them for at least 4 years. After the Taliban became an actual "thing" the US shifted its support to the northern alliance/northern warlords such as Dostum and Massoud.
