What if Ukraine is Gog from the land of Magog (Russia)?
Remember who Gog was in the Bible. I suspect that God is talking about actual descendants of that person rather than the current residents of a particular geographical area. The invaders will not be carrying around their genealogies with them, but God knows who they are.
Gog was the king of Magog
In Ezekiel 38, Gog is an individual and Magog is his land;
2 Son of man, turn your face against Gog[b] of the land of Magog, the chief prince of Meshech and Tubal, and prophesy against him.
Doubtful, but who knows?
