Story of U.S and Iran Relationship … “Four Days in August”

https://www.npr.org/2019/07/10/740510559/four-days-in-august

The U.S. and Iran have had a tense relationship for decades — but when did that begn? Over the next two weeks, we’re exploring the history. This week, we feature our very first episode about an event from August 1953 — when the CIA helped to overthrow Iran’s Prime Minister.

After listening to the NPR segment …. Please offer your thoughts on the following questions :

• 1.Why in August of 1953 was their a coup d’état (an overthrow) of the democratically elected government of Iran ? ….
• 2. Who was the chief “outside” country that was involved in that coup ? ….
• 3.Why might OIL be considered a curse for Iran ? …. (Briefly explain the story … Be sure to identify the agency that was involved in this covert operation)
• 4. Fast-forward ahead to 1979, when the U.S. and Iran are engaged in an American hostage crisis in Iran … How are these two events linked ? (Be sure to describe the role of the U.S., the Shah, and the religious clerics in this event)
• 5. When the hostage crisis is eventually resolved more than a year later, what happens to the future foreign relations between Iran and the United States ?
• 6. Why does the knowledge of this historical event matter to the current relationship today ?
• You should be able to plainly see how this situation that began nearly seven decades ago still has real relevance to our current situation with Iran and to our lives today !
