The Bomb had been in the making for forty years.*
In 1943, at Quebec, FDR and Churchill merged their countries’ nuclear research into the Manhattan Project based at Los Alamos in New Mexico. Now as Stalin arrived to visit Truman (finding him ‘neither educated nor clever’), neither man mentioned the test. ‘I didn’t know then,’ said Stalin, ‘at least not from the Americans.’ He had known since 1942, informed by Soviet spies. Until the explosion neither Stalin nor Truman could conceive of Trinity’s world-shattering significance. Learning from their spies about Trinity and knowing that their agents had secured uranium from Nazi laboratories near Berlin, Stalin and Beria twice discussed how to react if Truman informed him; they agreed to ‘pretend not to understand’.On 24 July at Potsdam, Churchill attacked Stalin for his aggressive actions in Romania. ‘An iron fence,’ he said, trying out the phrase that would become the Iron Curtain, ‘has come down.’
‘Fairy tales,’ replied Stalin, getting to his feet. Truman hurried after him; Churchill, pre-warned, watched.
‘The USA,’ said Truman, ‘has tested a new bomb of extraordinary destructive power.’
Not a muscle moved in Stalin’s face. After the fanatical Japanese resistance on Okinawa and the expectation that attacking Japan itself could cost 268,000 American dead, Truman planned to use the new weapon against Japan.
‘A new bomb!’ said Stalin. ‘Of extraordinary power. Probably decisive on the Japanese! What a bit of luck!’ Back in Ludendorff’s house, Stalin briefed his henchmen that Britain and America ‘are hoping we aren’t able to develop the Bomb ourselves, but that’s not going happen’. Stalin had already put Beria in charge of the nuclear project, but now this was ‘Task No. 1’. The race to catch up was on.
On 6 August a B-29 bomber named
Hirohito was shaken but did not immediately surrender; he procrastinated, seemingly more shocked two days later when Stalin invaded Manchuria. At dawn on 9 August, another American B-29 –
On 30 August, General MacArthur arrived in Tokyo, charged by Truman with preserving Japanese stability, while trying the militarists for war crimes. Tojo was executed, but MacArthur then decided to keep Hirohito, undoubtedly guilty too, by recasting him as a non-divine constitutional monarch.
