Before you suspect, you're right, I am afraid the repeat of WWII. and I fear the rise of authoritarianism in the UK with the leader of the opposition Jeremy Corbyn who's in a position to usurp power.
Well, as they say, those who forget the past are doomed to repeat it. But it would be more accurate to say that the danger is in not learning the right lessons from the past. For example, how many today actually know that immigration was one of the main contributing factors to the financial Depression, both in the U.S. and in Europe, and the German entrance into WW2 ? (albeit probably not the primary factor) Do we ever see that in textbooks? So obviously we're not learning the right lessons. Mass poverty and people ending up destitute and close to starvation was one of the major agitations for the war (although much of that may have been indirectly caused by the previous war, ironically). Some could argue that it was the very same policies Europe is trying to implement today that is what set the stage for the tensions in Europe leading up to WW2. Notice how, throughout past periods of history, Europe is trying to correct itself, from one radical extreme to the other. Go back in history much further and look at what Europe had before Nationalism swept the political landscape. Relatively speaking, Nationalism was regarded as a good thing by most of the people, on the whole (although of course there were many negative things too). It meant freedom from autocratic empires, and more defined political boundaries that, so the idea went, would lead to fewer large scale conflicts between empires without defined boundaries. But of course some of the nations began behaving like empires. Who knows what it might have been like if those multinational autocratic empires still existed though, could have been worse.
