WWI and WWII delayed going to the moon by 30 years. It was initially the British Empire that was going to go up there.

You failed to discredit my mention of trains and cars.
You cannot discredit the steam engine, refrigeration, electricity, vaccination and numerous other advances that had nothing to do with war, conflict or as you originally put it, violent upheaval, i.e. rebellion.
And need I remind you that the only successful rebellions in history were backed by people with power, not peasants with pitchforks?
