Before&After Nagasaki

Before(Top)
After(Bottom)

After the bombing of Hiroshima, three days later, "Fat Man" was dropped on Nagasaki. The second bomb was dropped was done to convince the Imperial Japanese army that surrender was their only option. Otherwise they would have fought to the death and millions of Japanese and Americans would have died in the invasion of Japan.



Six days after the detonation over Nagasaki, on August 15, Japan announced its surrender to the Allied Powers, signing the Instrument of Surrender on September 2, officially ending the Pacific War and therefore World War II. Germany had signed its Instrument of Surrender on May 7, ending the war in Europe. The bombings led, in part, to post-war Japan's adopting Three Non-Nuclear Principles, forbidding the nation from nuclear armament. The role of the bombings in Japan's surrender and the U.S.'s ethical justification for them, as well as their strategical importance, is still debated.
