Bearing in mind everything I know about France 1930s is from Russian history books and I don’t have confirmation off hand in American history books - as far as THOSE can be trusted - this is what I know about French history at that time.
1) France having survived World War I, barely, strove to drive out all forms of violence and competition from their lives and their children. Guns were rounded up and destroyed. Competitive sports no longer had winners and losers, everyone was a winner who participated. School fights were severely disciplined and all forms of martial training were eliminated.
2) France, having barely survived World War I, and having no imagination what-so-ever, built the Imaginary Line (Magino Line, or however you spell it) thinking if they were attacked, it would be similar to World War I.
Compare that to what Hitler had the Germans doing in the 1930s. (note, this really covers from 1917 until 1939, so a 22 Year Period, I am just using the 30’s to reference the entire period.) He had youth groups doing martial training, he had nationalistic pride instilled in children as young as 5 years old, he built up civil and military war machines, etc.
Just interesting. I know Germany eventually lost, but could the entire affair have been negated if France had allowed their children testicles and England had Winston as Prime Minister in the 1930s instead of Neville?
