Oppenheimer, Truman and the Bomb

What happens to a world that has abandoned a Christian worldview and has reverted to a science that does not fear God? Scorched earth warfare came back with a vengeance in the civil war under the military leadership of Sherman and Sheridan, and continued through the 20th century. The modern humanist-scientist developed a technology that could destroy a fairly large percentage of the world's population rather quickly. J. Robert Oppenheimer and Enrico Fermi are responsible—more aligned with a secular materialist, agnostic, and Hindu worldview than a Christian worldview. Then, Truman and Stimson were responsible for pushing the buttons. Nimitz, MacArthur, and Eisenhower were not supportive. But the more fundamental question is: How does this stand up against Deuteronomy 20?
