This is the primary thing. Their air force could be one of the best in the region, with Saudi Arabia and Israel a distant 2nd and 3rd, but... it's not. I can't really explain why, but my opinion is that the "allied forces" trained the Afghani forces with the intention and assumption of maintenance being taken care of for them. The pilots are fine, the mechanics are fine, the ground crews are fine; the supply chain is not, and Right to Repair issues still exist despite the circumstances.
