Fascism Compared to Communism

Why is it that Germany's fascism lasted a relatively short time compared to Russia's communism? The regimes established under Hitler and Stalin were incredibly similar with respect to the rise and control of the state. Both systems were based on entirely different ideology and goals. Hitler's Mein Kampf established the superiority of the German race and the need to expand as wanted by God. Hitler wanted the world. The government in Russia established by Lenin …

…systems of thought were very similar. But as one can see, the aspirations were radically different. Hitler was a threat to everyone and needed to be dealt with. Russia kept to themselves and bothered no one. A Cold War ensued with Russia complete with the irrational fear of Communism, McCarthyism, and a peace time build up of weapons followed. Germany was crushed in battle and Russia's Iron Curtain is being pulled down as I write.
