Eh, Armenia losing its war wasn't particularly detrimental to the Russian interests in the Transcaucasia - if anything it helped bring Pashinyan back into the fold, as evidenced by him embracing CSTO during the Kazakh unrest.

Minsk is also hardly "swallowed by protests" right now, they've succeeded in driving all resistance back underground.

I agree that the post-Soviet world is in a bit of a crisis but it's not particularly more crisisy than normal. Putin's just getting older.
