How did the Battle of Okinawa affect President Truman’s decision to use the atomic bomb against Japan?

The Battle of Okinawa was extremely costly, and Japanese forces continued fighting fiercely rather than surrendering. Truman and other US leaders took this resistance as a warning that an invasion of Japan could cause enormous casualties. This helped support the decision to use the atomic bomb; Okinawa did not show that Japan was close to surrendering or that the US could easily defeat it.
