The most recent and ‘top of the resume’ is that they were in charge during the Afghanistan withdrawal. That’s all that needs to be said in the firing.
These firings will ripple all the way down through the ranks. Clear down to the enlisted ranks. The everyday times are changing. You can’t pass gas in the halls of the pentagon without the word hitting the engine room on a ship in the Indian Ocean. The military has a network that fires info and rumor through at light speed. It’s been that way a long time before I served and that was a long time ago.
