If you were to go back to, say, 1913/14 and look at the political climate in Russia and Europe, it might be eye opening.
Then fast forward to 1931,or 2, and look close at the poitics of Europe, you might get a bit bug eyed, comparing what was happening then and what is happening now.
I doubt there will be a world war three, similar to the first two, in the next year, but it wouldn't be a surprise.
We are already involved in a world war, just nobody wants to admit it.
