As an “azeri”, I agree, the situation is a shitshow. Both nations lived together in many of these territories and you can’t just draw a line to separate them. I don’t know what a practical solution to this issue would be. Currently, the nations dislike each other, to put it mildly. But I have to say that since Azerbaijan recaptured their internationally recognized territories, there at least has been a ray of hope, because the leaders actually starting talking to try to solve things. There was 0 progress for almost 30 years and suddenly, there is some (no way you would see Pshinyan and Aliyev smiling on the same photo before then). As soon as the primary instigator (Russia) got busy enough, there’s progress started.
And while Azerbaijan is obviously not completely in the right here, considering the treatment of the prisoners and such, the western support for Armenia is mostly due to political reasons and not because Azerbaijan’s actions to reclaim their internationally recognized territories are inherently wrong. France and USA both have a lot of Armenian voters which influence their decisions, so the situation is rather skewed in the media. They bark to get the votes, but do nothing, because they want the oil/gas, and cause the territories are legally Azerbaijan.
Both parties are historically at fault and it was beneficial to keep them fighting.
