Truman's American empire

Since the Cold War ended Nato has ceased to be purely defensive and the USA has been very aggressive indeed. 

The present teaches us about the past and now the creation of Nato seems not purely defensive but also the creation of an American empire.

The cold war and the arms race were unnecessary as George Kennan said. I saw the cold war was unnecessary in the 1980s. 

He opposed the creation of Nato. I thought that Nato was what the UN was intended to be and had kept the peace. I was grateful to the USA for Nato but I wanted peaceful coexistence with the Soviet Bloc. 

Stalin had no intention of conquering Europe, as Hitler did. We don't know that Hitler had intended to conquer Europe rather than recapture lands lost by Germany and Austria in 1919 and conquer Russia, until England and France went to war with Germany but that it another story.
