After the second bomb was dropped there was a failed coup d'état by factions in the Military who STILL DID NOT WANT TO SURRENDER.
This is not speculation this is fact backed up by direct testimony of those involved in the coup as well as documentation from that era.
7 days later Emperor Hirohito announced the surrender of Japan in a radio address to the nation of Japan.
Anyone who sez that Japan was about to surrender is full of sh!t!
"Towards the end of World War 2 the Japanese military created and employed the `kaiten`, a manned suicide torpedo designed to blow up American ships with great accuracy. At that point in the War Japan had suffered severe losses, was experiencing rapid decline in its industrial capacity compared to the US, and American troops were closing in on the home islands. Surrender was out of the question, so Kaiten (along with kamikaze planes) were brought in to help tilt the balance."
