Aren't they kind of both to blame?
I do see the point Biden's rep made - that whether the troops pulled out now, or in 5 years or 10 years, the same thing would probably happen.
It's why I kind of find the whole 'blame the west' argument a bit difficult. Sure, every country has played its part and must all step in to help - I don't dispute that. We've made things worse not better. But the root issue is also the Taliban. And I do agree that it was a pointless war and we should never have gone over there. So in that sense, yes, blame the west.
Now, it's how countries like the US, UK, Russia etc use the Taliban and have done previously which helped them get so much power in the first place.
I want every single member of the Taliban, who wants to enforce Sharia law, and extremist views, wiped off the face of the planet. They are evil, they are monsters. In my mind that's what we should to to war to fight against. But I know real life doesn't work like that.
