Overview: This week President Truman and his aides meet to discuss the use of the atomic bomb. In Japan, the imperial government vows to fight on even as Yokohama is turned to ash by firebombing. On Okinawa, Japanese 32nd Army withdraws from the defences of Shuri Castle but there is still plenty of hard fighting left for the Americans. There are US Navy command reshuffles and the stage is set for an Allied conference in Potsdam.
