I'm open to having my mind changed if there's some evidence I missed, but the US has been offering money, training, and equipment for many years now.

And I’ve already mentioned to you that having bigger and better shooty shooty tubes isn’t the only thing that wins wars. This whole narrative (peddled from both the left and the right) that Afghans are a bunch of cowards who didn’t fire a single shot to stop the Taliban out of their own fear is abhorrently misguided, especially when considering that many of them were literally ordered to stand down by their own commanders and were tricked into thinking a peace agreement had been reached. Military capability (or rather, lack of it) =/= support for an invading regime. France did not consent to being ruled by Hitler just because it lost a war against his Wehrmacht.

If the Afghanistan people were willing to fight for democracy, they had ample opportunity.

They did. Tens out thousands of them both did fight and die for it.

As far as I can tell, that's the wide consensus opinion. It's on you to prove that's wrong if you believe it is.

Burden of proof fallacy.
