Its almost comical to watch Trump threatening all these wars when at the end of the day social inequality is so bad that effectively there is no one to draft. The typical cannon fodder of yore have been so beat down they would last 15 minutes or less on a battlefield. The only ones healthy enough to serve have parents rich enough to by their way out of a draft. You can't do a ground invasion with just drones manned by chubby kids with joysticks in a bunker. Corporate America has been so ruthlessly effective at pushing through such brutal levels of inequality that its actually become an existential threat to national security.
