The US wanted to develop a weapon before the Germans did, and fortunately had the scientists and resources to build one. Many key individuals came from European countries impacted by the war.
In 1939, just before World War II, physicists including Albert Einstein had written a letter to President Franklin D. Roosevelt about the possibilities of a "bomb" releasing fission energy from a critical mass of uranium. After the war broke out, FDR became concerned about the possibility that Germany could develop such a bomb, and in 1941 created the OSRD (Office of Scientific Research and Development) to investigate further. By 1942, the far-flung efforts were placed under the military command known collectively as the Manhattan Project.
He developed the theory of general and special relativity (E=mc2) which led to Robert Oppenheimer and his team creating the atomic bomb. The project was known as the Manhattan Project
Countires will have a race to build atomic bombs of their own, or fear the U.S. but only one is highly likely.

The atomic bomb was invented in 1933 by Leo Szilard while crossing a street in London and patented the following year. For many reasons he was not able to build it at the time by himself.It took 12 years before the US was able to build the first atomic bombs and use them to end WW2.
To defend against a possible Nazi atomic bomb!
1945
J. Robert Oppenheimer & general Leslie Groves
the atomic bomb led to the surrender in the pacific
the us created the atomic bomb
The original reason that the US began the project to build the atomic bomb was fear. Fear that Nazi Germany would build one first and use it to take over the world.After the war ended the US and USSR built them out of fear of each other.
The US drops the atomic bomb on two Japanese cities.
There were a number of top secret programs to build an atomic bomb. If you mean the secret plan of the US, it was called the Manhattan Project.
Einstein
The fear that Germany was already well on the way to building an atomic bomb and could make first use of them against either England or the USSR at any moment.
If you consider the US atomic bomb is a Christian bomb, the French atomic bomb is also Christian bomb and so on, then you can name the Pakistani atomic bomb an Islamic bomb.
The allieds (US, UK and Canada) called the project to make the Atomic Bomb was called the manhattan projecty. It started on 13th August 1942 and was abaloished in August 15th 1947.
