Because they were really peaceful and not really trying previously?
Or because you don’t grasp that the US had pulled back from major combat operations already years ago, the ANA was doing the fighting… until Biden pulled the rug out and they quickly collapsed/Taliban advanced.
You clearly have a complete logical disconnect here. The Taliban being largely peaceful before the deal does not, in any way, mean that they would not have launched attacks if the US decided not to fully withdraw as promised.
Also stop with the "pulled the rug" nonsense, It makes no sense. If the US committed to a full withdrawal, the "rug" was getting pulled at some point or another.
Irrelevant. There is no guarantee of anything here. Back in reality though, there were plenty of likely better options here.
Haven't seen one, from any one, especially from the arm chair generals in this thread, yourself included.
Its very easy to sit behind a keyboard on a computer forum, whilst literally knowing virtually nothing about the situation and just assuming that an objectively better outcome existed.
