No. You miss one very important difference. Russia may control territory easily, because we spoke the same language, because there are a lot of loyal to Russia Ukrainians, especially from older generations. It clearly visible on taken territories - great cooperation and no resistance.
Current regime dismissed over 20 political parties, had to close more than 50 TV and radio stations for to keep itself in power. They not only forbid Russian language, but even clear libraries from Russian books, and I mean books written in Russian language even if writer is giant of Ukrainian culture like Gogol. It is so funny: Gogol wrote his books in Russian. Bulgakov was citizen of Kiyev - capital of Ukraine, also wrote all his books in Russian, but now their books are in the fire.
