The simple fact of the matter is this..
You do not EVER withdraw the military first and leave thousands of your own people left to fend for themselves in a hostile state....simple they (the military) are last out and you either take your gear with you or scuttle it.
This has a stink all over it, in much the same way as Benghazi was handed over to Terrorists by Obama AND Biden weirdly enough with US citizens, a small Embassy security force and Ambassadorial staff left behind to be murdered without any military rescue. Eerily similar.
The CCP cant wait to get their hands on the trillions of rare earth minerals under the ground in Afghanistan.
The US oligarchs were only interested in the easy Billions of $ to be made on Opium, and non stop warfare.
The bonus for the CCP is they not only likely get their mitts on the mineral wealth of Afghanistan or a huge chunk of it to help the Afghani's mine it and process it, but they've also got the bonus of new high end US Military hardware which can be reverse engineered and copied.
This is a disaster for the Crash Test Dummy in Chief.
