Personally, I am convince that if the US Military ever lost a conflict because of PC policies, it would not do an honest evaluation of the situation. Rather, it would conclude that the loss was because it was not PC enough. In fact, I shudder to think how bad things would have to be for the Elites to change course.
The military at this point is preparing for war by remote; I don’t believe politicians will be putting “boots on the ground” in any numbers any time soon - or ever again. Much of the military is just a jobs program now - and used to protect the occupied capital when an election is stolen from the American voters.
If they think white boys are gonna jump in and fight their next war they got a another thing coming.
