Was it successful? 6. THINKER: What is an arms race? How could this be dangerous to American security?

2. The Cold War Arms Race

3. In the Beginning… After the U.S. dropped nuclear bombs on Japan, the world wanted their own nuclear bombs. After the U.S. dropped nuclear bombs on Japan, the world wanted their own nuclear bombs. This started an arms race: competition between two or more countries for the best armed forces. This started an arms race: competition between two or more countries for the best armed forces. Each country competes to produce larger numbers of weapons, greater armies and military technologies. Each country competes to produce larger numbers of weapons, greater armies and military technologies. UK, France, US, Soviet Union, and People’s Republic of China all produced nuclear weapons. UK, France, US, Soviet Union, and People’s Republic of China all produced nuclear weapons.

4. Soviet Power American experts had believed that the Soviet Union would not have nuclear bombs until the mid 50s. However, the Soviet Union tested their first nuke in 1949 American experts had believed that the Soviet Union would not have nuclear bombs until the mid 50s. However, the Soviet Union tested their first nuke in 1949 The first bomb that the Soviets tested was named Joe-One and the project was classified as “First Lightning”. The first bomb that the Soviets tested was named Joe-One and the project was classified as “First Lightning”. The whole world watched in shock at the Soviet Union’s new weapon. The whole world watched in shock at the Soviet Union’s new weapon.

5. Joe-One, the Soviets first nuclear bomb, was a copy of the American bomb, Fat Man. Joe-One, the Soviets first nuclear bomb, was a copy of the American bomb, Fat Man. Although it was a copy, it was much weaker. Although it was a copy, it was much weaker.

6. Soviet Program VS American Program Both parties believed that more nukes = more power! Both parties believed that more nukes = more power! Soviet Union built more nuclear weapons with cheaper quality. Soviet Union built more nuclear weapons with cheaper quality. Americans built fewer nuclear weapons, but with better quality. Americans built fewer nuclear weapons, but with better quality.

8. Hydrogen Bomb Both countries worked frantically to produce the first hydrogen bomb. Both countries worked frantically to produce the first hydrogen bomb. The US detonated the first H-Bomb in November 1952. The US detonated the first H-Bomb in November 1952. The Soviets exploded their H- Bomb in August 1955.

19. Mutual Assured Destruction At the end of the Kennedy Administration, both the US and the USSR admitted their vulnerability because of nuclear equality.

21. End of the Arms Race Economic problems led to arms control agreements beginning in the 1970s. This period of time, known as détente. Economic problems led to arms control agreements beginning in the 1970s. This period of time, known as détente. Détente: Both countries reduced their nuclear spending and stockpiles. Détente: Both countries reduced their nuclear spending and stockpiles. Strategic Arms Limitation Talks (SALT): limited the amount of nuclear weapons produced.

Limited Test Ban Treaty: banned nuclear testing above ground to prevent radiation poisoning Limited Test Ban Treaty: banned nuclear testing above ground to prevent radiation poisoning

23. Post-Cold War As the Cold War warmed up, the U.S. and Russia began to cut down on spending; fewer weapons were produced. As the Cold War warmed up, the U.S. and Russia began to cut down on spending; fewer weapons were produced. Large amount of resources and money which was spent on developing weapons was spent on repairing the environmental damage produced by the nuclear arms race.
