The war in Afghanistan was almost never well managed, but the withdrawal became an ignominious retreat and an absolute disgrace of uncoordinated, ill-conceived, morally bankrupt failure. It's shameful how America abandon Americans in the country as well as Afghani Christians, women and anyone else who believed that the country had a hope for a real future. Instead, the walked away and handed the Taliban the victory.
This lack of knowledge is highly indicative of the failures of the administration and excuses for the same.
