During the reign of the USSR, Russians settled in many of the captive lands. Ukraine has the most commonality with Mother Russia, and Putin is playing that up, but they are a separate nation. The Estonian population, for example, is 25% Russian. In the mid-90's, I became aware of and marveled at an underground Methodist congregation in Estonia that survived communist rule. With the fall of communism, it was amazing to follow their story, to see them thrive and develop the Baltic Mission Center that established a base for a congregation and a training site for pastors and missionaries. They have both an Estonian and Russian speaking service there.
@TerryP Economic - Biden will change his tune, again, about U.S. LNG exports. Every day Europe goes without Russian gas aids those exports. it would be nice if this helped a few pipelines from PA to the Atlantic seaboard see success - of course the libs would howl over that. Cutting off some access to world payment systems will bite. I haven't checked aluminum prices, but a Russian oligarch is huge in that space. Look who is just behind him. It's not
always about what someone will get out of something, though. Sometimes bad people pursue evil courses. Personally, I believe Putin recognizes his mortality and he wants to be known as the second (and true) father of the USSR, and he has always been a gambler as well. I don't believe this helps Biden or the Dems in the midterm. It's too far away, and the stupid voters have poor memories.
Strategic - Someone noted the Baltics could be next. That's a shooting war since they are now NATO members. Of course, Clinton committed to protect Ukraine in exchange for them giving up their nukes. That did them well. Biden blinked on China during the presser today, and he also signaled lack of European support on SWIFT, which makes sense because they are a seller to Russia for many goods and not just a buyer.
It's a big mess and no one world ruler is sufficiently courageous to counter the daring and brutality of Putin. We have Chamberlains and precious few, if any, Churchills in charge.
