The Cold War
How it affects us today
Ayatollah Ruhollah Khomeini
Ayatollah was the leader of the Conservatives who was supposed to establish an Islamic state. He resented the U.S. ideals and was a strong follower of Communism. He allowed his soldiers to storm the U.S. embassy and take 60 hostages. This was the first time an embassy was stormed and hostages were taken.
In the 1970's, there was a Muslim revolt that threatened to topple the Communist regime; the Soviets invaded in retaliation. The way this still affects us today is because the U.S. trained the members of Muslim resistance, and after the Muslims drove out the soviets, they attacked the U.S. in fear of being invaded again.
After he overthrew Batista, Fidel established the first Communist country in the western hemisphere, Cuba. Because This was the first Communist country in the western hemisphere and that it was so close to the U.S. it concerned the U.S. and they trained anti Castro soldiers to attack. However they were defeated and there was an embargo on any trade, and/or interaction with Cuba.
This was a war between the Americans and the Vietnamese in which the U.S. was forced to withdraw their forces in 1973. This was one of the first wars in which America was forced to pull out during the war.
The United Nations
The United Nations was created after world war 2 to continue fighting against the Axis Powers even after the war. Even now their job is to help stop the spread of Communism and to fight against the Soviet Union.
