The Russian Federation expansion did not generally use the traditional method of invading armies crossing borders, but it manifested itself through the simple expedient of calling on local peoples of Russian ancestry to ask Mother Russia for help. Mother Russia was of course happy to go and help them, and shoot all the nasty terrorists who threatened them. It was a simple matter after that to run new elections, and one region or entire nation after another joined Russia of its own free will. Russian observers were always happy to make certain that the elections were fair of course. It was all very legal. Very proper. Very Russian. The Russian Federation and all the Russian people were one big happy family again.
