After extending the original May deadline (for what reason?) and then underestimating the enemy and allowing the entire takeover in Afghanistan whilst also sitting there 'stunned' and doing nothing about it, isn't it too late for 'a plan' given all the time he had to think about it?

Might as well collect your belongings and leave Afghanistan in shame.

After that deadline extension, there is no pointing fingers at anyone else; it's on him this time. Unless you want to go back to how this 20 year war started in the first place with him and others voting for it?
