During World War II, the race to prevent Nazi Germany from acquiring nuclear capability gained immense urgency. Scientists and intelligence agencies from Allied nations, particularly the United States and Britain, embarked on a covert operation known as the "Tube Alloys" project. They intercepted German scientists, deciphered Nazi communications, and launched a sabotage mission against the Norsk Hydro plant in Norway, a critical source of heavy water for nuclear reactors. These efforts, along with the Manhattan Project's successful development of the atomic bomb, played a pivotal role in deterring Hitler from using nuclear weapons and ultimately preventing the Nazis from gaining a devastating advantage in the war.
