Question

On August 6, 1945, the bomber Enola Gay dropped the first atomic bomb used in war on the city of Hiroshima, and Japan:
surrendered
refused to surrender, so another atomic bomb was deployed
took the Philippines
burned Iwo Jima

Answer 1

Even though the devastation caused by the atomic bomb was tremendous, and had killed hundreds of thousands of Japanese citizens, the Emperor refused to back down. Surrender in the Japanese culture is shunned very harshly as it made one cowardly.  

Answer 2

Japan did not surrender, and another atomic bomb was deployed in the city of Nagasaki on 9 August.

The Japanese did not know that it was the only atomic bomb rest from the USA but decided to surrender on 14 August.

In Hiroshima 70,000 Japanese died, and 40,000 more in Nagasaki.
