There is no mention of a superiority complex in any of the definitions in the dictionary. We are not discussing superiority complexes we are discussing Imperialism. You're response however is a perfect example of anti-imperialism. This belief that by conquering or taking control of a government there will automatically be superciliousness taking place and the country conquered would be better off on it's own.
