The Afghan government and army were absolutely rational when failed instantly

The Afghan government and army were absolutely rational as investors during the crisis. If a fall is inevitable, then you need to get out of the process as early as possible. How could one assume that the Afghan army would fight if its defeat was inevitable, as everyone predicted it? Even a fool will understand, but apparently not the American intelligence, that resistance to the Taliban will lead to an immediate and long-term increase in the risk of being killed or going to jail. The very assumption that the army, doomed to inevitable defeat, will fight in order to justify analysts that it will hold out until winter, borders on the madness of the puppeteer in relation to the puppet.
