Belarus openly joining Russia in war against Ukraine with troops deployed tonight.
Putin putting strategic nuclear forces on heightened alert and explicitly threatening use of his 500 SSBN missiles against US and Western Europe as response to the economic sanctions.
Europe providing and funding arms supplies to Ukraine, escalating up to now include (reportedly) fighter jets, and giving permission for nationals to join fight in Ukraine against Russian invasion. French foreign legion allowed release of Ukrainians, with gear (possibly), to join fight.
While this ain't WW3 quite yet, things are heading that way, with Putin continuing to escalate and showing no signs of backing down.
Not impossible that Putin tonight starts massive bombardment of civilians in Kiev or another smaller Ukrainian city to try to force Ukrainian surrender, if that happens, West is running out of options now - short of direct military intervention.
