Not entirely false. Taliban was initially formed by Pushtun students of Pakistan Medrese. By coincidence, they were the core of resistance to the Soviet army. Mohammed Omar, founder of Taliban, was a veteran of Anti-Soviet war. So, not entirely a time travel case.

Yes, entirely false. The fact that a veteran of some group later did something else doesn't mean everyone involved in the first venture contributed to the second.

That's like saying Peter Thiel founded Tesla. It's so obviously false that anyone pushing that narrative is presumptively dishonest.
