Colonel Groves was an extraordinary man. He and his scientists, and industry were The Manhattan Project. He managed it. He knew he could not make those brillient scientists from talking about the bomb. Thus he isolated them in near luxury in the mountains of New Mexico, Los Alamos. His great scientists were mostly European Jews that fled Germany and Eastern Europe because of Hitler. The oddity of it all in WWI these same Germans were loyal citizens and loyal to the Kaiser. As loyal Germans they would have built the bomb for Hitler if they had not been persecuted by Hitler and the Third Reich.
His hatred of Jews oddly gave the weapon to the USA first and not Germany. If he had been rational he would have won WWII.
Didn’t know he hated Jews.
