War is a cruel thing i know.
What you continue to say is plain and simple, if German would have won we World would be a better place.
Instead I am just trying to make you see that, between all the contraddictions of Usa and British 1940's society, that fortunately time has solved letting us see and hope a better place, especially for us different people, these two countries along with resistence forces inside Italy and French, and with Russia, whose democracy is still a puzzle, have guaranteed us freedom and a little of self respect and identity.
Now you can add what you want, our democracy are still full of privilegies and sometimes very unfair, but totalitaristic regimes are based and founded just upon the idea of the negation of the citizen identity toward his appartenence to the nation, and can only live as long as they proclaim theyr hate on others (muslims, hebrews, christians, gay, transgender, polonian, french, americans, it really doesn't matter who or when ).
That's why luckily totalitarism is a thing of the past, and our next goal is try to improve democracy, allowing more respect for the people and less for the money.
As for Italy, you really know nothing about it, Mussolini memory is full of shame, and he is remembered with prode just by few naziskins or ignorant people here. Communism never took place in this country, luckily, and we had our trouble with right politicians tring to create a populistic regime (that was, in our case, like a totalitarism just based on the control of media and not on the control of police repression forces), it just led us to an unfair democracy and a closed society, from wich now we must move on.
By the way multiculturalism is a great resource, if you're not closed minded, all human history is luckily based on mixture of races, it is called evolution. It all depends if you just see the problems or the advantages, multiculturalism means more ideas, more need to improve, more competition, that if all the rules accepted, means a more dinamic society (that is basically why Usa in just 10 years won the second world war, become the leader of the world, and why now Cina wants to do the same). Democracy and capitalism balanced with rules is all we can hope for the future, unless we want to live in a shamefull past.
