Is It Just That Eucranians Are White?

i've encountered people who know nothing about politics, who suddenly feel so moved and have such strong feelings right now. Is it just that eucranians are white? Or is it more that russia is the enemy? What what makes this war so relatable and resonant to to americans? I wish people felt a more universal sense of solidarity with people who suffer but and who are oppressed. But this global sentiment must be difficult to watch from yemin or palestine.
