Western European nations have gotten a pass in recent history because they've been deferential to the US, are liberal democracies (ideologically aligned), and are not especially rich in strategic assets like oil. The same could be said of South Korea and Japan, highly civilized and in ideological alignment with the US.

In its history the US has engaged in military action against western and white majority nations: Great Britain (twice), the Confederate States, Spain, Germany (twice), Italy, and Yugoslavia. Not mention the perpetual rivalry against Russia/Soviets since the end of WW2 which has meant doing things like backing the "brown" mujahedeen against the predominantly "white" Soviets. Today it backs Ukraine against Russia, arguably making that war of "white" nations more deadly than it otherwise would be.

The US may have never fought against lilly white Scandinavian countries but neither has it done so against "brown" India or sub Saharan Africa.
