Iran has been a conundrum since its 1979 revolution. It stunned the world by introducing Islam as a form of modern governance, and rattled the region by exporting its zealous ideology. It supported militant allies and challenged international norms. For decades, dealing with the Islamic Republic was complicated by internal repression, menacing rhetoric, and defiance over its nuclear program. USIP conducts research and policy analysis on Iran, and Institute experts regularly brief Congressional staff and U.S. officials.

The move was the latest in the Trump administration’s “maximum pressure” campaign to cut off Iran’s revenue streams and push Tehran to negotiate over its controversial nuclear program. The waiver dates back to President Trump’s first term.
