But also much stupider.
They were told they were going to war to "make the world safe for democracy."
Could anything have been further from the truth?

There was no democracy. Not in Canada, not in the US, or France. Certainly not in Britain. The masses of Brits lived lives that were cruel, brutish, short, oppressed, repressed, and impoverished. But, yeah, men could vote. (lol).

The British Empire was cruel, brutish, and long, very long.
WW I happened due to cut-throat imperialist competition among the European empires to conquer and exploit African nations. The arms race that accompanied the imperial competitiveness land grabs made war inevitable.

  We cannot avoid more useless, futile, stupid bloodbaths if we avoid knowing the truth about those we managed to survive. History always repeats. It will take a huge co-operation among nations to avoid a third world war. So far, that isn't happening. Time to top making war seem so glamorous, honorable and attractive.
