It is interesting to look at Ukraine in the context of what is happening in other countries – Putin instigated the events in Kazakhstan and seems to have his eyes on a full occupation of Belarus (though how would we even tell at this point).
In addition to ordering US citizens to leave Ukraine, they have also been advised to leave Belarus.
I am not sure this figure is correct, but it is certainly a lot. The US sent an armada recently when Putin slowed transmission in the pipeline to a trickle.
I suspect few Americans realize that Ukraine is the “bread basket of the world.”
