At this point, it doesn't even matter which president we blame for this. The reality is that we will have to return to that absolute sh*thole and fix the problem as it will become both a humanitarian crisis and a national security threat before the end of the fall.
The 75,000 Taliban just grew to 375,000 Taliban minus the ones that managed to flee the country. Anyone else will pledge loyalty or die. The border is about as open as our southern one so terrorists with an interest in war are now flooding into a military training ground for bad people totally uninhibited by a government we can pressure or sanction to death.
The Taliban and Al Qaeda are well known for ruthlessness when it comes to torture, rape and murder. Any woman that taught in an American built school will be stoned and any little girl that attended, likely raped and potentially turned into slaves. Any military aged male either has the choice to join up and fight or will die a pretty horrible death along with their families.
One things for certain, the intelligence community and military leadership totally dropped the ball on this as they should have understood the 300,000 person army would fold like a lawn chair and they should have had some intel that the Taliban were going to advance. There should be outrage over this.
