For me the concern in discussions like this is that it seems like the implication is that if Americans aren't constantly ripping our hair out and rending our clothes over the genocide of the American Indians, we have no right to decry modern genocides, or something?

Americans don't need to rip out their hair and rend their clothes. Americans need to give land back to tribal governments and pay reparations to Black people. Americans can then pay reparations to other marginalized minorities and other countries that the US has destroyed (Vietnam, Laos, Cambodia, Afghanistan, Iraq, and so on)

It was absolutely evil what the US government and the governments of the several States did to the American Indians. Just like it was evil what the US government and the governments of the several States did to black Americans. And it was evil when the US government decided to drop nuclear weapons on Japanese civilians twice after Germany was defeated, instead of for example near Japan but with no human fatalities. And on and on.

So where are the reparations then? "Oops I made a big boo-boo" doesn't fucking cut it. Vietnam still has victims dying from Agent Orange. Laos still has millions of UXO littering their country. But has the US foot the bill to clean up the mess they caused? Of course not.

But that doesn't make it not evil or less evil what, for example, Putin is trying to do to Ukraine right now.

The US has killed far more people than Putin. Hell, Dubya alone has killed far more people in eight years than Putin did in his entire life. Orders of magnitude more people.

Or the various military coups in Africa right now.

Most of those coups are anti-French coups with popular support because no one there wants to be ruled by the French. It isn't a threat to democracy if some neocolonial puppet who's only there due to rigged elections got kicked to the curb by anti-French military officers.

And an American ought to be able to criticize those things and call for peace without having to list every evil thing America has ever done first. And the evil things that America has done shouldn't prevent individual Americans from calling out evils that they see.

Talk is cheap. When is the US going to actually do something about it? Where's the forty acres and a mule Black people were promised for turning on their plantation slavemasters?
