Dayton, they spent most of the Obumma years literally PURGING themselves of their top rank generals who held to the old standards of fighting men, god and guts in lieu of woke commanders who supported women and gays in the military at the front lines over top fighting men, and who supported the whole gambit of progressive ideology and ploys. Then they fired all of the soldiers who likewise did not hold sway with these things, would not accept the politicization of the military, the globalist views of the left, in any way showed support for Trump or the belief that America was that shining city among nations, even those who chose not to get the covid vaccine.
In other words, the military has purged itself of its best commanders and soldiers in lieu of people who held sway with their political agenda to such a degree that many retired early and won't come back and now, few even want to sign up for.
The current Joint Chief is so bad that at one point a couple years ago when he got some crazy notion that Trump might lead a military attack against China of some kind, CALLED China to warn them! He went around his commander's back and told them if anything came down, he'd give them a heads up. In other words, he viewed NATO or the UN (global governance) as his true commander and the POTUS as secondary and subordinate to the "greater good."
That is treason, and the military (and fed) are so bad now that he was never even reprimanded much less fired!
