Also, the French I think suffered so much during WWI that they almost preferred peace at any price. I reread the “Rise and Fall of the Third Reich,” it was either Keitel or Jodl that noted when Germany invaded Czechoslovakia, the French has 80 divisions to Germany’s six or seven on the Western front. If France invaded in response to that attack, Germany and Hitler would have fallen.
