He strikes me as more a rube that occasionally picks up alt-right talking points than a dedicated follower. At least on one occasion he called out Moon, a shitty right wing video essayist, for lying, but he went really hard on anti-Sweet Baby Inc. content.
So I guess he could unintentionally? But intention doesn't really matter here. His fanbase probably leans right too.
I think the Ukraine situation does more to increase the favorability of military spending than anything with China.
But mostly I think America being late to intervene in WWII still hangs over the American public's heads (to me it would seem this is the point when anti-interventionism stopped being the norm.)
