The trial can only end in a mistake because it is founded on one. How can a foreign court try a sovereign government of another country? Could we have tried your President Franklin Delano Roosevelt and Secretary Henry Morgenthau, or Winston Churchill and Anthony Eden, if we had won the war? We could not have done so and would not have. And trying that went on would have to be done by the nation itself and the courts set up there.
