is that it has been reduced to the enforcement arm of the current socio-political order.

That's pretty much it. After 1945, there has never been a single justified war for Western nations.

Invading Korea, Vietnam, Iraq, Cuba, Afghanistan, Panama, Libya etc has only made life worse. Imagine being a soldier, coming back from the horrors of war, just to experience demographic replacement, LGBT education in schools, rampant inflation, low wages etc.

Never join the armed forces. If anything, be hopeful the current system collapses faster instead of shedding blood for it.
