the Incomparably Shrewd and Clever
Good points all, but I will echo this. As I mentioned upthread, as Russia's economic outlook gets tighter, those abstaining today will see that handouts from Russia will shrink/dry up in the future as Russia continues this course of action. They should see their best interest lies with Russia ending their behavior as soon as possible and acting like a 21st century nation. Unfortunately, it may take a long time for this to become evident, and even once their client states recognize it and begin to vote against Russia, it may take a long time for Russia's behavior to change (if ever). Umbran has the right of it, sadly; UN intervention action requires the Security Council (not the UN General Assembly) approval, and as long as Russia has a veto, it will never pass.Meanwhile, those abstaining at this point are generally doing so because Russia gives them something that they want/need, that they stand to lose if they cheese Russia off. You want them to make symbolic gestures that won't change the situation, except for their being left in the lurch for something they need?
This slow pace and building pressure is one of the most frustrating aspects of economic sanctions in the face of brutality.
