I think this is more of a case of them just feeling invincible.
Like how putin was sure he would roll over ukraine in a week. Only to later find out that his military is a paper tiger. Full of ghost divisions, ghost equipment, etc.
With communists in charge of the USA. they do what comes naturally, which is to hollow out any institute they can.
They are sure there is an infinite supply of loyal troops and that the USA army is invincible. So nothing stops them from fucking around.
Besides, they own the media. So "surely" they can memory hole it and make sure the active servicemen do not find out.
