Azerbaijan invaded Nagorno-Karabakh in 2023 and now all their enemies are gone (disarmed and Armenians expelled) which presumably makes their citizens better off once they move into the empty territory.
Two things to note there. One, many did make a peep; I have friends, coworkers who both ardently discussed and even pointlessly protested in small groups with signs.
The other - I don't pay taxes to the Azeris, every moment of my productive life doesn't support the genocide there, and my soul is in some way not as blackened by the atrocities there. I think people care about Palestine because they rightly feel complicity. Maybe Russian citizens - whose labor indirectly goes to supporting Azeri atrocities - are up in arms?
So I shouldn’t say it never happens.
