It seems rather ironic that the nation who dealt the harshest sentences on Nazi officials was itself a totalitarian nation guilty of its own crimes. The Soviet Union collaborated with Germany to carve up Poland in the early stages of the war. The USSR also used the trials to blame responsibility of the Katyn massacre on the Nazis, a claim later to be challenged and dropped by the American and British judges after evidence pointed that it was in fact the Soviet NKVD who committed the killings.
Other intriguing occurrences in the trials are shown below:
The court agreed to relieve the Soviet leadership from attending these trials as war criminals in order to hide their crimes against war civilians, war crimes that were committed by their army that included "carving up Poland in 1939 and attacking Finland three months later." This "exclusion request" was initiated by the Soviets and subsequently approved by the court's administration.[77]
Freda Utley, in her 1949 book "The High Cost of Vengeance"[81] charged the court with amongst other things double standards. She pointed to the Allied use of civilian forced labor, and deliberate starvation of civilians[82][83] in the occupied territories. She also noted that General Rudenko, the chief Soviet prosecutor, after the trials became commandant of the Sachsenhausen concentration camp. (After the fall of East Germany the bodies of 12,500 Soviet era victims were uncovered at the camp, mainly "children, adolescents and elderly people."[84])
The Tribunal itself strongly disputed that the London Charter was ex post facto law, pointing to existing international agreements signed by Germany that made aggressive war and certain wartime actions unlawful, such as the Kellogg-Briand Pact, the Covenant of the League of Nations, and the Hague Conventions.[avalon 25]
The main Soviet judge, Iona Nikitchenko, presided over some of the most notorious of Joseph Stalin's show trials during the Great Purges of 1936 to 1938, where he among other things sentenced Kamenev and Zinoviev.[86] According to the declassified Soviet archives, 681,692 people arrested for "counter-revolutionary and state crimes" were shot in 1937 and 1938 alone–an average of over 900 executions a day.[87]
So clearly, the Nuremberg trials incorporated and dealt with highly controversial actions. Do you believe that these actions were necessary in order to bring the Third Reich to justice? Or did they make a mockery of law and create double standards on the victors?
I believe that while the trials did serve a noble cause, the allied nations did engage in war crimes themselves. The US waged unrestricted submarine warfare against the Japanese (though this charge was later dropped from the Nazi defendants), and the Katyn massacre was used as a tool to cleanse the Soviets of all responsibility. Whether or not the Allies should have themselves been tried is a question I am unable to answer.
