I feel like libs largely save those kinds of arguments for the domestic working class though. Imo, applied to international relations they're too openly eugenicist for most libs. Conservatives will openly argue that stuff, but libs tend to just echo imperialist propaganda when it comes to anyone that the US foreign policy blob deems to be an enemy, while pretending that all the dictatorships that they are creating/propping up are 'burgeoning Jeffersonian democracies' or some other bollocks
