You realize Trump was the one who set up the deal and the timeframe for the Afghanistan pull out right? He even bragged about sticking Biden with it. The Taliban were upset when it went over the date and upped their already regular attacks.
And in fact to your last point about trusting America, Biden was trying to stick to the agreed upon deal.
Wrong. Biden welched on the deal Trump made. The same day he did that, Taliban began attacking.
The fustercluck withdraw from then on was all Biden's fuck up. All Biden had to do was honor the previous terms and use the previous plans, then the pull out would have gone off without much drama.
And in fact to your last point about trusting America, Biden was trying to stick to the agreed upon deal.
