Estonian is not Finnish but it belongs to the same language family.
Putin's actions are in keeping with a long line of Russian rulers such as Peter the Great and Catherine the Great. During the Soviet period the question sometimes was posed whether the Kremlin's actions were part of the desire to spread world Communism or just in keeping with traditional Russian expansionism.
It was Khrushchev, not Stalin, who added Crimea to Ukraine.
