From an article in the October 5, 1946 edition of The Economist (est. 1843) entitled The Nuremberg Judgment
In 1939 Moscow openly gloried in military cooperation with Germany for the destruction of Poland, "that ugly offspring of the Versailles Treaty," and Ribbentrop in his last plea quoted a cable of congratulation from Stalin as proof that the Soviet Union had not then regarded the war against Poland as an aggression. The contrast between 1939 and 1946 is indeed fantastic, and it is too much to expect that either historians in the future or Germans in the present will share in the current United Nations convention of not seeing it.
Nor should the Western world console itself that the Russians alone stand condemned at the bar of the Allies' own justice. Waging aggressive war is the chief count in the indictment, but it is not the only one. Among crimes against humanity stands the offence of the indiscriminate bombing of civilian populations. Can the Americans who dropped the atom bomb and the British who destroyed the cities of Western Germany plead "not guilty" on this count? Crimes against humanity also include the mass expulsion of populations. Can the Anglo-Saxon leaders who at Potsdam condoned the expulsion of millions of Germans from their homes hold themselves completely innocent?
The result of the Nuremberg trial has been a well-deserved fate for a group of evil men whose terrible guilt has been thoroughly demonstrated for all time; yet the force of the condemnation is not unaffected by the fact that the nations sitting in judgment have so clearly proclaimed themselves exempt from the law which they have administered.
