Of course the possibility of Putin resorting to nuclear weaponsIs is becoming higher by the day as he becomes increasingly more cornered and Ukrainians are pushing ahead.. Now one thing I hope for is that Putin's disastrous mobilization will open the eyes for many and the change will come from within which will stop the escalation and hopefully avert the major disaster. I hear that change had already started happening as there is some discontent growing over failing war in Kremlin and they openly talk about it in Russian state media.
