I don't think Joseph Stalin will object to the original plan of Nuremberg Trials.
Quoting the wiki:
On 1 November 1943, the Soviet Union, the United Kingdom and the United States published their "Declaration on German Atrocities in Occupied Europe", which gave a "full warning" that, when the Nazis were defeated, the Allies would "pursue them to the uttermost ends of the earth ... in order that justice may be done. ... The above declaration is without prejudice to the case of the major war criminals whose offences have no particular geographical location and who will be punished by a joint decision of the Government of the Allies." This intention by the Allies to dispense justice was reiterated at the Yalta Conference and at Potsdam in 1945.
British War Cabinet documents, released on 2 January 2006, showed that as early as December 1944 the Cabinet had discussed their policy for the punishment of the leading Nazis if captured. The British Prime Minister, Winston Churchill, had then advocated a policy of summary execution in some circumstances, with the use of an Act of Attainder to circumvent legal obstacles, being dissuaded from this only by talks with US and Soviet leaders later in the war.
The demise of the Morgenthau Plan created the need for an alternative method of dealing with the Nazi leadership. The plan for the "Trial of European War Criminals" was drafted by Secretary of War Henry L. Stimson and the War Department. Following Roosevelt's death in April 1945, the new president, Harry S. Truman, gave strong approval for a judicial process. After a series of negotiations between Britain, the US, Soviet Union and France, details of the trial were worked out.
One thing is beyond any doubt: Dolfie will be severely beaten and bruised by the catchers unit.
