No, relations with Cuba were not improving. The Obama administration was working to undermine the Cuban political project, and both the Obama admin and Biden admin continued the sanctions regime on Cuba. Biden performatively removed Cuba from the state sponsors of terror list right at the end, because he knew it would get struck down. You also clearly have not spoken with indigenous peoples. Making token gestures is not at all the same as respecting prior treaties and decolonizing Turtle Island.
I care deeply about the struggles in Cuba, Palestine, and indigenous struggles here. I devote my time and money to organizing for a better world, because I know these are not problems that can be solved under capitalism. Minority nationalities shouldn't be your pawns for political rhetoric. Get in the streets, get organized, and stop treating the tokenizing of minorities under democrats that then perpetuate their butchery and oppression as liberation.
Do better. Join an org, and stop defending the capitalist class and their cronies.
