Trump's agreement was based on conditions on the ground, he would have never pulled out our stabilizing force seeing the Taliban advance as we drew down.
The Taliban broke the agreement, not the US.
Joe is 100% responsible for the criminally negligent manner in which we pulled out giving them billions in our best weaponry and an intact airbase.
Worse, he flat out abandoned tens of thousand of SVH holders promised entry into the US and thousands of US citizens in the way he tucked his tail and ran.
A phased withdrawal would have been the only acceptable plan that would have then allowed for those tens of thousands of people to leave before our Troops ran for the planes and skedaddled leaving them all to fend for themselves.
