Not likely to escalate to WW3. Has echoes of what spread across Twitter after the assassination of Soleimani two-years ago. Obviously Russia invaded Ukraine before in 2014 and have remained a feature on the borders for the Ukrainians for the last 7-8 yrs. An invasion does seem to be odds on but Putin’s overall objectives don’t correspond with pursuing an all out war. Is more likely to be a strongarm tactic to facilitate discussions with NATO concerning the 1000 mile shared border with Ukraine and his aspirations to restore what was lost when the Soviet Union crumbled.
