The Arms Race
After the USA used nuclear weapons to defeat Japan in World War 2, the Soviet Union began to focus on building its own nuclear weapons and a 'nuclear deterrent'.

1940s - The USA leads
- On the 6th and 9th August 1945, the USA dropped atomic bombs on Hiroshima and Nagasaki, to defeat Japan and bring them to surrender.
- This ended World War 2.
- On the 29th of August 1949, the Soviet Union completed its development of an atomic bomb.
- The USSR was 4 years behind the USA with its nuclear capabilities.

1950s - The USA leads
- In 1952, the United States successfully built a Hydrogen bomb.
- Experts estimate hydrogen bombs to be 1,000x more destructive than the atomic bombs used in Japan in 1945.
- In 1953, the USSR built their own Hydrogen bomb (H-bomb).
- They were now only 1 year behind the USA.

1950s - Neck and neck
- Atomic bombs and hydrogen bombs were important because they allowed countries to do lots of damage to their enemies.
- Missiles became very important because they allowed countries to remotely fire lots of missiles at their enemies quickly.
- The atomic bombs over Japan were dropped from planes.

1950s - Neck and neck (2)
- In 1958, the USSR completed a test of an Intercontinental Ballistic Missile, called an ICBM.
- These missiles could be fired 5,500km (the distance from Lisbon to New York over the Atlantic Ocean).
- The USA developed ICBMs in 1959, but the USSR had taken the lead in the Arms Race.

Mutually Assured Destruction (MAD)
- Whilst the Soviet Union didn't have nuclear weapons (before 1949), the USA knew that in a war, it could use nuclear weapons and win.
- After 1949, both the USA and USSR had nuclear weapons.
- After 1959, both sides could fire nuclear weapons 5,500km at each other.

Mutually Assured Destruction (MAD) 2
- If there were to be a nuclear war between the 2 countries, it is likely that both countries would be completely destroyed, shooting missiles at each other.
- This concept was called Mutually Assured Destruction (MAD).
- This made using nuclear weapons seem like a worse option.
