Russian polls mean nothing at all. In summer 2015 90% of Russians knew nothing about Syria and how it is different from Pakistan or Morocco and in autumn 2015 they overwhelmingly supported operation in Syria to save Assad.
Simply now in Karabakh Russia can't do very little so their diplomacy and propaganda is keeping low profile. They allow even pro Azeri opinions.
But still they do small things they can:
* They activated attacks in Syria.
* They sent their soldiers to Armenia-Azebaijan border. Even though Azerbaijan never planned to cross it that gives Armenia some confidence and allows to free troops and send them to other places.
* They send some weapon supplies through Iran.
Overall stubborn position of Armenia made them 100% dependent on Russia. Everything in Armenia belongs to Russian companies: electricity, communications, transport... This creates huge corruption and poverty. Pashinyan was first Armenian leader in 30 years who started fighting corruption. But then he was accused of being a US/Soros agent so in order to counter these accusation Pashinyan started showing his extreme "patriotism".
Ironic, if Armenia loses Karabakh completely it will be the best thing happened to them. They can start concentrating on Armenia itself: fight corruption, start trade with Turkey and Azerbaijan, cut military spends and became more or less a normal country.
On the other hand if Azeri victory wont be decissive, then things in Armenia will get even much worse: corrupt leaders will return to power, they will boost military spends and nationalistic histeria.
