Why was Hiroshima chosen?

Hiroshima was chosen because it had not been targeted during the US Air Force's conventional bombing raids on Japan, and was therefore regarded as being a suitable place to test the effects of an atomic bomb.

How many people did the atomic bomb kill?

The bombs immediately devastated their targets. Over the next two to four months, the acute effects of the atomic bombings killed between 90,000 and 146,000 people in Hiroshima and 39,000 and 80,000 people in Nagasaki; roughly half of the deaths in each city occurred on the first day.

Which country has the most powerful weapons in the world?

Statistics and force configuration

Country	Warheads (Deployed/Total)	Date of first test
The five nuclear-weapon states under the NPT
United States	1,600 / 6,185	16 July 1945 ("Trinity")
Russia	1,600 / 6,500	29 August 1949 ("RDS-1")
United Kingdom	120 / 215	3 October 1952 ("Hurricane")

Which country was the first to make nuclear weapons?

France exploded its first nuclear device in 1960 and China entered the "nuclear arms club" in October 1964 when it conducted its first test.

Who won the arms race?

In the last decade of his life, Einstein dedicated himself to the cause of nuclear disarmament. "The war is won," he said in December 1945, "but the peace is not."

What led to the Manhattan Project?

The Manhattan Project was the code name for the American-led effort to develop a functional atomic weapon during World War II. The Manhattan Project was started in response to fears that German scientists had been working on a weapon using nuclear technology since the 1930s—and that Adolf Hitler was prepared to use it.

Who knew about the Manhattan Project?

The Manhattan Project employed over 120,000 Americans. Secrecy was paramount. Neither the Germans nor the Japanese could learn of the project. Roosevelt and Churchill also agreed that Stalin would be kept in the dark.
