The Manhattan Initiative

The United States, the United Kingdom, and Canada collaborated on the top-secret Manhattan Project during WWII. Its primary objective was to develop an atomic bomb before Nazi Germany could. The project’s scientific director was designated as physicist Robert Oppenheimer.

Robert Oppenheimer’s Role

The success of the Manhattan Project was primarily attributable to Oppenheimer’s brilliance and vision. He was critical in keeping the project on track and coordinating the operations of various scientists.

The Dilemma of Building the Bomb

Ethical Considerations

As the atomic bomb neared completion, Oppenheimer and his team were faced with a moral quandary. The immense destructive power of the bomb raised serious ethical questions about its use as a weapon of war.

Psychological Impact

The responsibility of creating a weapon capable of such devastation took a toll on the mental well-being of Oppenheimer and his colleagues. The weight of their actions and the potential consequences of their work haunted their thoughts.

The Aftermath of the Bombing
