It wouldn't surprise me if he goes for other nearby countries, such as Belarus, Sweden or Finland, western countries that do not belong in the NATO and could potentially be an easier target. He has already threatened Finland and Sweden if they decided to enter NATO...
You missed everything, Russian troops are already in Belarus. History shows that where Russia has sent its troops, they remain there forever. It is from the territory of Belarus that the offensive is now underway on the capital of Ukraine, the city of Kiev.
