You're practically advocating a Final Solution that Europe is so inherently incapable of governing itself that it should be subjected to full-scale Germanization and German dominance. To take over Europe would, realistically speaking, be the worst possible idea ever formed. Germany must be brotherly with her fellow nations, not needlessly racist, supremacist and antagonistic.
Germans aren't perfect, and they certainly aren't the übermensch you pretend you are. Italians aren't perfect either, neither are Franks, Russians, et al.
If your spiteful behavior is an indicator of the average German's attitudes towards other ethnic groups, then perhaps Italy has been too long under your jackboot, you feckless thug.
