Yes. We did learn.
We learned that when men such as the Nazis pose a threat to the world, the time to deal with them militarily is in the early stages (in the case of Hitler, when he renounced the Versaille Treaty) instead of waiting until they cause the deaths of 40 million people.
All you Germans have learned from the 20th Century is to die by the millions when the German cause was the enslavement of Europe and to now cower like children when the cause involves fighting against those who would enslave others.
We learned that the Nazis that fought to enslave Europe needed killing in the 1940's and we learned that the Baathists who are now fighting to re-ensl;ave Iraq need killing now.
