  19. "ATTENTION JAPANESE PEOPLE" EVACUATE YOUR CITIES *Because your military leaders have rejected the thirteen part surrender declaration, two momentous events have occurred in the last few days. *The Soviet Union, because of this rejection on the part of the military has notified your Ambassador Sato that it has declared war on your nation. Thus, all powerful countries of the world are now at war against you. *Also because of your leaders' refusal to accept the surrender declaration that would enable Japan to honorably end this useless war, we have employed our atomic bomb. *A single one of our newly developed atomic bombs is actually the equivalent in explosive power to what 2000 of our giant B-29's could have carried on a single mission. Radio Tokyo has told you that with the first use of this weapon of total destruction, Hiroshima was virtually destroyed. *Before we use this bomb again and again to destroy every resource of the military by which they are prolonging this useless war, petition the Emperor now to end the war. Our President has outlined for you the thirteen consequences of an honorable surrender; We urge that you accept these consequences and begin the work of building a new, better, and peace loving Japan. *Act at once or we shall resolutely employ this bomb and all our other superior weapons to promptly and forcefully end the war." EVACUATE YOUR CITIES (This message was sent to the residents of Nagasaki before the second bomb was dropped.)
