if they hadn’t had to fight in WW2
But that's not what he is saying. You are saying it like if Germany didn't start WW2, The Farage adviser is saying it like if they had just let Hitler win.
HUGE difference. And if you claim what the adviser is saying is not crazy, what would you think it would look like if Hitler had won?
Fascism throughout Europe, which could spread to UK and USA, like English and American values spread to Europe because they won.
I know fascism is spreading in USA now anyway, but imagine how bad it would be if the Nazis had won!
