Part I: Topic Overview & Fill in the Blanks

In August 1945, the United States dropped atomic bombs on Hiroshima and Nagasaki, killing approximately 210,000 people by year's end — the culmination of a firebombing campaign that had already destroyed 67 Japanese cities. In the months that followed, the Allied powers attempted something unprecedented: rather than summarily executing the defeated leadership of Nazi Germany and Imperial Japan, they convened international tribunals at Nuremberg and Tokyo to establish legal accountability for aggression, war crimes, and crimes against humanity. These trials produced genuine legal achievements that shaped international law for the next seventy-five years. They also protected some of the most consequential perpetrators — including Emperor Hirohito, the Unit 731 biological warfare scientists, and over 1,600 Nazi rocket engineers and scientists recruited under Operation Paperclip — whenever Cold War strategic calculation made accountability inconvenient. This lecture asks the central question: can justice ever be achieved after total war, or does power inevitably determine who is held accountable?

Complete each statement using the lecture deck. Bold terms appear in Part II.

  1. By August 1945, the U.S. had firebombed   Japanese cities; Operation Meetinghouse alone killed   civilians in a single night — more than the immediate deaths at Hiroshima.
  2. The Manhattan Project was authorized in 1942 because of intelligence that   was pursuing nuclear weapons; it employed approximately 130,000 workers at Oak Ridge, Hanford, and Los Alamos.
  3. Sixty-nine Manhattan Project scientists signed a petition urging Truman not to use the bomb without warning; the petition was classified and suppressed by  , and Truman never saw it.
  4. Hiroshima was not a military base — it was a civilian city of approximately   residents, chosen as a target because it was large and undamaged enough to demonstrate the bomb's destructive power.
  5. The most legally innovative charge at Nuremberg was  , designed specifically to capture the Holocaust — acts committed by a government against its own citizens.
  6. The tribunal established as binding precedent that   is not a defense to crimes against humanity — a principle now embedded in military codes of conduct worldwide.
  7. MacArthur shielded Emperor Hirohito from prosecution to stabilize Japan as a Cold War ally; Hirohito reigned until   and was never required to account for his role in the war.
  8. Unit 731 received full immunity from prosecution in exchange for   shipped to Fort Detrick; its scientists returned to civilian life and some had distinguished postwar careers in Japanese medicine.
  9. Under Operation Paperclip, Wernher von Braun — an SS officer whose V-2 production killed approximately 20,000 concentration camp laborers — became director of   and received the National Medal of Science in 1975.
  10. In October 1978, Yasukuni Shrine's chief priest enshrined fourteen   war criminals from the Tokyo Trial, including Hideki Tojo, making them divine spirits whose enshrinement is theologically irreversible.

Part III: Pause & Reflect

These questions appeared on the lecture slides. Write a substantive response to each — full sentences, your own reasoning.

Section I — The Atomic Bomb

(Pause & Reflect)

By August 1945 the United States had already firebombed 67 Japanese cities. Operation Meetinghouse killed more people in one night than the immediate deaths at Hiroshima. At what point — if any — does the atomic bomb constitute a qualitatively different moral act from the conventional bombing that preceded it? Does the scale of the weapon matter — or only the scale of the killing?

Section II — Nuremberg

(Pause & Reflect)

The Soviet Union — which had invaded Poland, occupied the Baltic states, and conducted its own mass atrocities — sat as a co-equal judge at Nuremberg. Can a proceeding be politically compromised and historically legitimate at the same time? Does the presence of a guilty judge invalidate a verdict against a guilty defendant?

Section III — The Tokyo Tribunal and the Emperor Question

(Pause & Reflect)

MacArthur shielded Hirohito from prosecution to stabilize Japan as a Cold War ally. Hirohito reigned for forty-four years after the war and died without ever being required to account for his role in it. Does the stability that decision produced vindicate the compromise of accountability? What was the cost — to Japanese historical memory, to Chinese and Korean victims, to the Nuremberg principle that heads of state are personally accountable?

Section IV — Who Escaped Justice — and Why

(Pause & Reflect)

The United States prosecuted Nazi war criminals at Nuremberg and simultaneously recruited Nazi rocket engineers whose work was built by slave labor. It granted immunity to Unit 731 scientists for their research data. What principle governed these decisions — or is the only honest answer that power, not principle, determined who was held accountable?

Section V — The Japanese Paradox — War Criminals as Shinto Gods

(Pause & Reflect)

Enshrinement at Yasukuni makes Class-A war criminals into divine spirits. Japanese prime ministers who visit argue they are honoring all war dead, not specifically the war criminals. Is it possible to honor a nation's war dead while acknowledging that the war they fought was criminal? Or does the enshrinement of war criminals make that distinction impossible to maintain?

Section VI — The Limits of Victors' Justice

(Pause & Reflect)

Nuremberg tried some perpetrators while protecting others. The ICC prosecutes African leaders while the Security Council's permanent members operate outside its jurisdiction. Is partial justice better than no justice — or does it legitimize the underlying structure of impunity by providing it with a legal facade? Your answer matters — not only for 1945, but for every subsequent crisis in which the international community must decide whether to pursue accountability.
