The “all in” move was when they suggested they NATO not meeting their demands to permanently commit to excluding Ukraine and withdraw allied forces from Eastern European members of NATO was an aggressive act pushing them to war in Ukraine. When NATO didn't fold, they either had to invade or show the Putin regime as a paper tiger, which is a mortal blow for an authoritarian regime.
They spent many years on efforts to weaken governments of the West and relations between them for the purpose of doing something like that and having Western unity collapse. Maybe they misjudged and thought that would pay off.
