This is wrong. The US did not give weapons to the Taliban (voluntarily). If you mean Operation Cyclone their receiver was not the Taliban but the mujahadeen, which, yes, consisted of Taliban, but also of enemies of the taliban (northern alliance)
The Northern Alliance contain some people who are probably even worse than the Taliban so while you are technically right I am not sure it matters.
