The current administration aren't really isolationists. Hell, they've threatened buying/invading Greenland and the Panama Canal.

They're opportunists, protectionists, and authoritarians. I mean, Trump himself has praised Xi for ruling with an iron fist, and extending tenure 'for life', remarking he'd like to do the same. Musk would pretend to support democratic views if they were the dominant view of the current administration, or somehow thought it would benefit him. But like I said, they're opportunists - people who exploit current circumstances to gain immediate advantage rather than being guided by consistent principles or plans. They're not really isolationists...
