Why did the ideological differences matter? Considering the United States was isolationist before the World Wars, why did they suddenly care about the beliefs of a counter across the globe? (relative to geographic location of population)

They both had enough resources, land mass, and could’ve done their own things within their country. The Soviet Union closed off their territory via the iron wall anyways, so any gains in ‘exclusive‘ trading partners would be marginal.
