Fascinating man, really. If you do read the article - notice that while he resigned rather than follow orders to suppress a rebellion in Estonia, and there are streets named after him in the places that hate Russia, he also won elections with 90% of the vote once he became a warlord and disbanded parliament. History, it would seem, is not black and white.
