CK, look up august article by Henry Kissinger. He lauds the iitial campaign in Afghanistan, but thinks that attempts to install a Western democracy were doomed to begin with. He then separates problematic situation there from the final decision by Biden administration: Describing the evolution does not eliminate the callousness and, above all, the abruptness of the withdrawal decision.
he ends with this:
We must recognise that no dramatic strategic move is available in the immediate future to offset this self-inflicted setback, such as by making new formal commitments in other regions. American rashness would compound disappointment among allies, encourage adversaries, and sow confusion among observers.
The Biden administration is still in its early stages. It should have the opportunity to develop and sustain a comprehensive strategy compatible with domestic and international necessities. Democracies evolve in a conflict of factions. They achieve greatness by their reconciliations.
