Episode notes
Root of U.S.-Iran Tensions
- U.S.-Iran tensions significantly stem from a 1953 CIA-backed coup overthrowing Iran's elected prime minister.
- This historic intervention fostered deep Iranian distrust toward U.S. intentions, especially regarding control over oil resources.
Origins of Nuclear Concerns
- Iran's nuclear program concerns escalated in the early 2000s when it concealed nuclear sites from the IAEA.
- This concealment raised fears that Iran's civilian nuclear program could be a precursor to weapon development.
Impact of U.S. Sanctions on Iran
- U.S. secondary sanctions, targeting companies and countries trading with Iran, intensified in the 2010s.
- These sanctions significantly damaged Iran's economy and helped bring Iran to agree to the 2015 nuclear deal.
