Kinda? What exactly does Hosting mean? Did they know about the plan? Did they help in the planning?
Dude, we just watched a 20 year nation building exercise get completely exposed as a fraud, $2 trillion and supposedly the best trained army money could buy immediately threw in the towel against a lesser opponent.
Obviously, the establishment is trying to shift attention away from this and it seems to be working.
The Taliban hosted Bin Laden and his literal terrorist training camps in Afghanistan. Yes the Taliban knew exactly what he was doing. They protected him. They then refused to turn him over after 9/11. So yes, they are as responsible for the 9/11 attacks as Bin Laden.
Regarding the Afghan army, make sure you dig deeper than what the president and other talking heads are saying. We definitely wasted a ton of money on them, but it wasn't really a fighting force. It wasn't "300,000" soldiers. It was more like 30,000, many of whom where the dregs of society. The majority of them were potheads. They didn't really have much of a professional fighting force like ours. They were doomed to fail without our support, or least the support of civilian contractors (who President Biden abruptly pulled).
