Iran would have to be their second strongest supporter. Russia Created them and arms them for free.
I don't see Iranians as having race and religious superiority delusions. Not the ones I've met. I've met quite a few.
Mind you, the Armenians I've met have without exception been utterly descent, reasonable and polite people. and I've also met many of them. I cant figure out that such a people would be engaged is such injustice in their neighbourhood.
Interestingly, I've also met many turks, and a vast majority have been rude, violent and unpredictable and just plain crazy and neurotic. One guy keeps trying to shake my hand in the middle of the covid pandemic. I've been in physical fights with many. Maybe its a cultural thing, only decent ones I've met were a taxi driver that talked for an hour about how much he loves Erdogan (we had something in common there) and a turk who actually had Bosnian ancestry I met in Istanbul airport. So I don't know. politics does not always translate into good human to human relations.
