> BOTH SIDES HAVE TO BE READY FOR COMPROMISES TO SAVE LIVES

I agree with that in principle but I honestly can't see how to achieve that in practice in this situation. Russian leadership currently doesn't seem to care about internation rules. They believe themselves to have a sacrosanct right for greatness and the right to rule and bending to any compromise would be utterly unacceptable in that framing.

I don't think this as an absolutely Russian problem; it's the problem of super-powers that are no more (but still kinda are). I fully expect a similar situation to happen in the future when American will only be a shadow of the power it used to be.
