It's complicated. Dude certainly didn't regret defending American liberty, as any time there was fighting to be done he got back in, but he was pretty jaded from fighting to protect private interests in the Caribbean and South America.

He was an anti-fascist republican that supported FDR. He was from the political class, career military, private sector between wars, ran for office and lectured after he retired.

Bona fide war hero.

Interesting guy either way.
