Maybe it's because we created some super-double secret weapons to control Russia and China that we no longer need to have a military. What it is is still a mystery though. At the moment, all that China and Russia know is that recruitment in US military is way, way down and what little they are recruiting and training is being indoctrinated in all manner of garbage that has absolutely nothing to do with the mission. Notwithstanding that we are depleting our munitions by the boat load in the most corrupt country on the planet.
So it's only logical that it must be because we have some super-double secret weapons to control Russia and China. Otherwise, we should invest a few grad on gallows in Washington DC to weed out our own corrupt politicos and woke-assed idiots, which might just have the added benefit of reducing our taxes once more of the former are culled.
