Seventy-five years ago, on August 6, 1945, the world changed. With the dropping of the first atomic bomb, mankind had finally found a weapon that could wipe out the entire population, literally at once.

The United States started working on developing an atomic weapon after having been warned by Albert Einstein that Nazi Germany was already conducting research into nuclear weapons. By the time the United States conducted the first successful test (July 1945), Germany had already been defeated. But the war against Japan was still being fought.

President Harry S. Truman was warned by his advisers that any attempt to invade Japan would result in a horrific number of deaths–up to a million. So he ordered that the new weapon be used to hopefully bring the war to a speedy end. It was a decision that resulted in horrible deaths and unspeakable wounds.  However, it was the right decision.

Mushroom Cloud Over Hiroshima

On August 6, 1945, the American bomber Enola Gay dropped the five-ton atomic bomb over the Japanese city of Hiroshima. A blast equivalent to the power of 15,000 tons of TNT reduced five square miles of the city to ruins and immediately killed 80,000 people. Tens of thousands more died in the following weeks from wounds and radiation poisoning.

On August 9, three days later, another bomb was dropped on the city of Nagasaki, killing nearly 40,000 more people.

Nagasaki The After The Nuclear Bomb

A few days later, Japan finally announced its surrender.

Lately, there has been much revisionist history about the dropping of the atomic bombs on Hiroshima and Nagasaki. Some say that Japan was poised to surrender before these horrible weapons were dropped, that Truman did not have to use the Atomic Bomb. If this was the case, no one told Truman, or General MacArthur…no one told the Japanese Emperor either.

At noon on August 15, 1945, six days after Nagasaki was bombed, the Emperor of Japan announced Japan’s surrender over the radio. This was the first time in history the people of Japan had ever heard their Emperor’s voice. He blamed the surrender on the horrible new weapon.

The enemy, moreover, has begun to employ a new most cruel bomb, the power which to do damage is indeed incalculable, taking toll of many innocent lives. Should we continue to fight, it would only result in the ultimate collapse and obliteration of the Japanese nation . . . but would lead also to the total extinction of human civilization. Such being the case, how are we to save millions of our subjects, or ourselves, to atone before the hallowed spirits of our Imperial ancestors? This is the reason we have ordered the acceptance of the provisions of the joint declaration of the Powers.

The use of the atomic bomb to end WWII was as horrible as it was necessary. Two bombs ended up killing over two hundred thousand people, wounding countless others (and that doesn’t even include the birth defects), but it was still much less than what a land invasion would have caused.

Soon after the U.S. developed their atomic bomb, others developed the weapon. In 1949 the world was horrified as Soviet Russia tested a nuclear weapon. The world settled into what eventually became known as mutually assured destruction (MAT). No nation wanted to use nuclear weapons because any first strike could be answered with an equally destructive response.

Over seven decades later, nine countries have gone nuclear. Along with the U.S., there is Russia, United Kingdom, France, China, India, Pakistan, North Korea, and Israel (although officially Israel will not say whether or not they have nuclear weapons). Beyond those, we know that Iran is close to the weapon, and the terms of the JCPOA had no role in slowing it down. Saudi Arabia has been shopping for the technology to defend itself against a nuclear Iran.

By seeing the destruction, the repugnant human devastation of this weapon mankind may have worked even harder never to use it again. Thankfully in the seventy-five years since it was used, no country has dared to use these horrific weapons whose killing power has been refined and expanded.  But that may change as Iran moves toward the bomb which it may use itself or share with its terrorist partners
