Man's entry into the atomic age in 1945 created a long list of new ATOMIC weapons. From cannons firing atomic mini bombs (atomic artillery shells) to Intercontinental Ballistic Missiles (ICBM's). Other than the nuclear weapon ITSELF...the really new invention was atomic (nuclear) energy; such as nuclear powered submarines and warships.
You mean like United States and Australia??
The first atomic bomb was engineered in WWII, not the Cold War. The Hydrogen Bomb was a Cold War Weapon.
The United States and the Soviet Union developed the ability to completely destroy each other.
Any hostile nation with such a weapon puts us right back into the cold war; Tension.
H-bomb
All the states of the United States were.
There were actually many, the Soviet Union, People's Republic of China, United Kindom, I believe France, and the United States. In addition, Israel was also widely believed to have developed or received hydrogen bombs from the United States both now and today.
The dropping of the atomic bomb on Hiroshima and Nagasaki by the United States in 1945 heightened tensions between the United States and the Soviet Union, leading to the start of the Cold War. The Soviet Union saw the bomb as a threat to its own security and began its own nuclear weapon program, escalating the arms race and competition between the two superpowers.
United States and the Soviet Union
In Alaska, there are villages that are cold 24/7.
The Cold War developed in the Soviet Union, Europe, and the United States due, in large part, to the competition over the arms race and over scientific advancement during the 1970and and 1980s.
