Just watched a video hosted by some geopolitical pundits very well versed on that region, and Wow! talk about convoluted! As a quick summary, Armenia invaded and seized land they have a historical claim on back in the 1990's, right after the Soviet Union break up, which Azerbaijan also claims. The US (the west) supported the Armenians then, (the Clinton administration) and then pulled the rug out from under them so the Armenians couldn't advance further. In 2020 the Azerbijanians purchased drones from Turkey and used them to destroy Armenian forces...this was the first use of drones in actual combat, not just spying and surveillance...but they lacked the ground forces to follow up and Armenia was able to cling to its gains. So, today the uneasy stalemate exists, and the geopolitical scene is so jumbled, so confusing...Iran supports both Azerbaijan, for its Muslim ties, but also Armenia because of economic ties, and Turkey despises Armenia for its Christian historical ties and culture but doesn't want Iran to gain in economic power so has been trying to cut off those economic/commerce ties. Russia has supported Armenia but is presently in no position to do much to help, so Armenia has renewed its lobbying efforts in the US and Europe seeking aid, and this has pissed off Russia. Turkey supported Russia's help for Armenia, for reasons given, while at the same time opposing it as a member of NATO.
If all of this sounds confusing, it is actually much worse and more complicated than this. I just tried to give the Cliff Notes version
