How Hiroshima and Nagasaki were destroyed by America?


 

The bombings of Hiroshima and Nagasaki in August 1945 marked a turning point in World War II and a pivotal moment in world history. These events not only hastened the end of the war but also showcased the devastating power of nuclear weapons, forever changing international relations and military strategy.

Background to the Bombings

The United States developed nuclear weapons under the top-secret Manhattan Project, which began in 1939 and culminated in the first successful test of an atomic bomb on July 16, 1945, in New Mexico. By this time, Germany had surrendered, but the war in the Pacific against Japan continued.

Despite heavy conventional bombing and a naval blockade, Japan showed no signs of surrendering unconditionally, as demanded by the Allies. The prospect of a costly invasion of the Japanese mainland led American leaders to consider using the atomic bomb to force a swift end to the war.

Hiroshima: August 6, 1945

The Bombing Mission

  • The Bomb: The bomb, nicknamed "Little Boy," was a uranium-based weapon.
  • The Plane: The B-29 bomber Enola Gay, piloted by Colonel Paul Tibbets, carried the bomb.
  • The Target: Hiroshima, an important military and industrial city in western Japan, was selected as the primary target.

The Attack

At 8:15 a.m. on August 6, 1945, "Little Boy" was dropped over Hiroshima. It detonated approximately 600 meters (1,900 feet) above the city with an explosive yield of about 15 kilotons of TNT.

Immediate Impact

  • Destruction: The explosion destroyed nearly everything within a radius of 1.6 kilometers (1 mile), with fires spreading across 11.4 square kilometers (4.4 square miles).
  • Casualties: Approximately 70,000 to 80,000 people were killed instantly, with total deaths by the end of 1945 reaching about 140,000 due to injuries and radiation sickness.

Nagasaki: August 9, 1945

The Bombing Mission

  • The Bomb: The bomb, named "Fat Man," was a plutonium-based weapon.
  • The Plane: The B-29 bomber Bockscar, piloted by Major Charles Sweeney, was assigned the mission.
  • The Target: Nagasaki, a key shipbuilding and industrial center, was chosen as the secondary target after Kokura was obscured by clouds.

The Attack

At 11:02 a.m. on August 9, 1945, "Fat Man" was dropped over Nagasaki, detonating at an altitude of about 500 meters (1,650 feet) with an explosive yield of approximately 21 kilotons of TNT.

Immediate Impact

  • Destruction: The hilly terrain of Nagasaki limited the bomb’s destructive radius to 2.6 square kilometers (1 square mile), but the blast still caused extensive damage.
  • Casualties: Around 40,000 people were killed instantly, with total deaths by the end of 1945 estimated at 70,000 due to injuries and radiation sickness.

Aftermath and Consequences

Japan's Surrender

The combined shock of the bombings and the Soviet Union's declaration of war against Japan on August 8, 1945, led Emperor Hirohito to intervene. On August 15, 1945, Japan announced its unconditional surrender, formally ending World War II on September 2, 1945.

Long-term Effects

  • Health Impact: Survivors, known as hibakusha, suffered from long-term effects including cancer, chronic illnesses, and genetic damage. The psychological trauma also had lasting repercussions.
  • Reconstruction: Both cities were eventually rebuilt, with Hiroshima becoming a symbol of peace and nuclear disarmament. The Hiroshima Peace Memorial Park and Nagasaki Peace Park stand as reminders of the bombings.

Global Impact

The bombings highlighted the devastating potential of nuclear weapons, leading to a nuclear arms race during the Cold War and ongoing efforts towards non-proliferation and disarmament.

Conclusion

The bombings of Hiroshima and Nagasaki by America remain some of the most controversial and significant events of the 20th century. While they brought a swift end to World War II, they also ushered in the nuclear age, presenting both a dire warning and a call to action for future generations. The stories of these cities, their destruction, and their subsequent recovery continue to shape our understanding of war, peace, and the human capacity for both destruction and resilience.

What Are The Causes Of Climate Change?

  Today we are living in 21st century. Everything is modernized. The World is changing very rapidly. Temperature of planet Earth is increasing day by day, which is very alarming. Increase of temperature of Earth day by day is called Global Warming or Climate change. Where technology give comfort to human being, same in case it is harming the world. Like vehicles which we use today are for our comfort is damaging the atmosphere very badly. When vehicles run on the road, they emit harmful gases into the atmosphere. After that, harmful gases react with natural gases and harm the atmosphere of  planet Earth. These harmful gases have acidity, so when they react with Oxygen and Nitrogen in the atmosphere, they pollute it. These harmful gases make the atmosphere acidic and when rain fall on Earth it makes the rain acidic. When acidic rain fall on Earth, it destroys the soil fertility. Vegetables and fruits require fertility of soil to grow, so when fertility affected then growing of plants a
