We just handed the Taliban and Al Qaeda more than 6 SE drones, MRAPS, Humvees, M4's, M240's, MBT LAWs, 50 cals, NODS, a variety of sniper rifles...... etc. Those drones will be sold to China and Russia so they can pillage our technology and the rest gets distributed to fighting forces.
If we have to return to collect our 10,000 left behind Americans, things just got exponentially harder given we shutdown our most critical airbase and it's now secured and held by the Taliban. If surrounding countries decide not to help us, our fellow Americans could be in real trouble should the historically reasonable and diplomatic Taliban choose to slaughter them or keep them as hostages.
For those that seemingly want to blame a former president, the current one reversed every single policy Trump put in place his first several months in office......a new record of executive orders but he managed to keep this one. Afghanistan as a whole can be blamed on 3 presidents, maybe 4 if you count Bush but at this very moment, one president owned the exit plan that exponentially failed. There was no contingency plan. Those are just the facts.
