Not to mention the third-party plausible denability effect, through which arms may not have passed directly to "Muj" or Taliban, but were supplied by the US.
So to say the "Taliban" were never armed is completely factually incorrect, both in relevance to the Soviet war and the current one.
If you want to learn more about the US involvement as the number one arms dealer in the word, the revised Shadow Factory book is out and worth the long read.
By this logic the US has armed every one of its enemies. I said the US never armed the Taliban. You are saying that through enough backchannels and shifting alliances the US did arm the Taliban. Now who is being obtuse?

In the end one war ended and groups broke up. Then the next war came and alliances had changed.
