Thoughts on Hitler 

"The dictatorship of Hitler qualifies as a paradigm for the twentieth century. One way extreme and reflected, among other things, the assertion of a modern state, unexpected levels of repression and state violence, an unparalleled manipulation of the media to control and mobilization of the masses, cynicism who scored above the international relations, the serious dangers of ultra-nationalism and the tremendous destructive power of ideologies of racial superiority and the maximum consequences of racism, holding hands with the perverted use of modern technology and 'social engineering'. Above all, it was a beacon of warning that it continues to shine with all the intensity showing how a modern society, rich and educated can plunge so quickly into a barbarism which culminated in an ideological war, a conquest of brutality and greed that hardly could have been designed, coupled with a genocide that the world has never witnessed before. Hitler's dictatorship resulted in the collapse of modern civilization - a form of nuclear destruction in modern society. He showed us what we are capable”
