First the Taliban isn’t Russia/China. A decently trained and motivated army numbering in the hundreds of thousands should be able to deal with them, if not outright crush them.
The nations you reference would indeed be crushed also, but they would fight for their countries and the French and Brits have Nukes. Taiwan and S Korea would fight to the death. Not so with these people who believe they owe little or no allegiance to the so called nation state.
There should be recriminations over this failure. I have no problem with that concept. I also have no issue that there is a real argument that we should have stayed there notwithstanding the duration or cost.
I have zero doubt though that what’s happening now would happen whenever we leave, no matter how we do it.
