“We dropped the bomb not to get Japan to surrender, but as a warning to the Soviets. Of course, we didn’t realize that by then the Russians had already stolen all the information they needed to make their own bomb.”
Nope, FDR gave him that data and the yellowcake needed to produce same during WWII.
Read “American Betrayal” by D. West for the details.
So you are saying that Truman did know about the atomic bomb before and that the Manhattan Project didn’t have many spies? Because you are 100% wrong on that, Soviet archives proved what we already knew.
And you completely leave out the role Churchill had in getting the U.S. Churchill basically manipulated Roosevelt and got the Allies to become Stalin's butler. Churchill screwed over the U.S. more than any leader during WWII.
