" Unfortunately, most scientists were radicals, socialists, and liberals. There was hardly a conservative among them. And they believed that the truths discovered by science were for humankind to share, and should never be kept secret in the service of one regime or country. So while the American government was keeping this huge project top secret, the scientists held discussion groups about sharing nuclear technology with all the nations of the world. Oppie himself was suspect: the only reason he was not in the Communist Party was that he never joined clubs. "
