I get the ease of comparing everyone and everything you don’t like to Hitler/Nazi Germany but it’s a dumb comparison that minimises the holocaust.
Do people only count if they live in a “democratic” country then?
The US has invaded and interfered in other countries and their democratic processes above all else to protect US economic (and by extension political) interests in those regions, and/or to open up new markets for US capital (for consumption and for access to resources and cheap labor). Believing it’s about ideas like democracy or freedom (which are not binary or equally measured things) instead of profits/geopolitical influence is naive and ahistorical.
Have Iraq/Libya/Afghanistan become more democratic after US intervention? How about the many right-wing dictators and regimes the US military/CIA have helped take power (and used to eliminate anti-US/capitalist political groups, suppress elections, protect US businesses/land rights/resource extraction/military presence, destroy labor unions, push through austerity and other neoliberal economic programs, etc). It's never been about upholding/restoring democracy or improving the prosperity of the local population (has usually resulted in the opposite), but safeguarding/extending US interests.
Of course it’s not just the US that does this, but given their unique position as the leading superpower over the past century and a half they have had the most opportunity/capabilities/success at it, and so their list of victims is naturally longer. Now Russia is attempting to do something similar in Ukraine but using their own justifications that resonate with their population, in contrast to the US's favored democracy/freedom™ PR line, however beneath those layers of bullshit the underlying material reasons are the same (and just to be clear in neither case are justified, or excusable because it's been done before, but imperialists gonna imperialize).
