Isayas was deadly to his competition. He proved that again and again for the last sixty years. He created and decimated friends and foes along the way. Going back my main argument, Isayas pushed many Eritrean youngsters to Europe and the USA perhaps purposely. That benefits his government in two ways. Less opposition and plenty foreign currency. Many of these youngsters have been brain washed in Sawa. Hence he gains plenty of love and hate through these channels. Remittance from diaspora is a huge part of the revenue for his government. A lot of truck drivers who earn some $10,000 a month, most of them single, are an asset to him currently than bright youngsters who aim scientific and technical research for their future evil: Hitler was a fool. Stalin was just deadly. Isayas is a lot like you guessed it. Stalin himself. Sadame was a jerk, and Gadafi was just an adolescent fool. Abbiy is Gadafi with a comedian but far more devious prostitute like personality.
