I understand the support for Armenia in light of past Turk crimes against them, but I'm not gonna lie--I'm not really in Armenia's corner for this. I prefer to remain detached, but if I have to express an opinion on it; the territory does technically belong to Azerbaijan and the Armenian regime got themselves into this mess.
First, they decided to favor Western relations in Europe over Russia. So Putin is not really happy over the current administration's anti-Russian narrative. In addition to that, the Armenian government also made claims on Turkish lands. Finally, instead of continuing negotiations with Azerbaijan for a peaceful compromise, they began to build roads and populate the formerly dominate Azerbaijani regions with Armenians to both strengthen their hold and claim.
When you're a landlocked power and you piss off two major powers to the north and west, then proceed to flip off the more or less equal power to your east...well, you sort of deserve what you get.
The only power that they've got support from is Iran. Because Iran's northern region connecting there has a large amount of Azerbaijani and the Iranians have an informal agreement with Armenia as a way of keeping tabs on the region. And even Iran has had to scale back their support, because they're worried about rebellions in their minority-dominated areas.
So yeah, Armenia's government screwed the pooch on this.
