I agree entirely with Dave, war is a cancer on mankind and nothing good comes from it, - the end result of these wars should be the execution of those that caused them, - World War I was one of the greatest crimes in history, the most guilty were French, Russian and Eastern European politicians (Serbia in particular); what "guilt" Germany and Austria owned were due to misplace pride and naivety, - the Kaiser and German leaders should have been "culled" after the war, but so too should have the French and English criminals that were more responsible for the war. Woodrow Wilson should have decorated a lamppost, a true pig of monumental proportions, - possibly the worst President until the modern era...
Not to say that some good came didn't come from the war, the Hapsburg Empire was oppressive and long past its time, - often credited with tolerance for minorities, especially Jews but this is far to generous, the Hungarian's anything but tolerant of Jews or Rumanians, - the Germans of WWI were arrogant to minorities of Eastern Europe but as tolerant as any nation when it cam to Jews (those that attributed antisemitism to German character are full of shite, nazism has little to do with German character.. it is a sadistic "socialistic" ideology that has few similarities to "conservatism")
Anyway, war guilt and atrocities (and every war has them in plentiful supply) should be attributed to individuals (not nations or populations who are more often more victims themselves... who in America today, what remains of it, thinks the central government and their decisions or actions are reflective of their desires or interest? This was as true in 1939 Germany as 2022 America, - I strongly disagree with everything this "country" does or stands for today...), - WWI hanging of the Kaiser and his associated guilt ridden conspirators would have been appropriate as would the similar treatment of Russian (possibly the guiltiest of all in their corruption and causation of the war) and French politicians (hardly less revolting than the guilt of the Russians and Serbians).
I hope the movie is well done, but doubt it if recent experience is a clue, - especially Netflix (which gave millions to Scumbag Obama for nothing). better to read Remarque book in the original as he had a true appreciation of the value of war, it's meaningless, its legacy of harm to individual families, (mothers, fathers, sons, daughters and wives) for little more than obscure abstractions... how many Marines that fought and died on Guadalcanal or Okinawa ever heard of these shitholes in 1941, or cared, - sons of miners and farmers who get shite on by their governments should not have to be sacrificed for the ambitions of billionaire industrialist or political opportunists...
