Fascist governments always collapse eventually because of loyalty over competence, but the thought of the damage a powerful country like the US would do before that collapse is terrifying.

The US spends 3.4% of GDP in defence. Israel is at 5.3%. Also the US only spends a bit more then 3x what China spends and well US products are more expensive. So the US can probably fund its military for quite some time, without too many problems and right wingers love to do it, to bomb the shit out of people.
