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.

As neighbors with a 585-mile frontier, Iran and Afghanistan have connections spanning centuries. Since 1979—the year of Iran’s revolution and the Soviet invasion of Afghanistan—relations between Tehran and Kabul have ebbed and flowed. USIP’s Scott Worden discusses the complex relationship between the two countries, how Iran has built influence there, and where the U.S. and Iranian interests have overlapped in relation to Kabul.
As Iraq shapes a government from its May 12 election, the indecisive electoral outcome again will leave Iran in a position to affect both the choice of a prime minister, and the tenor of the underlying administration. How Iran wields that influence is likely to depend on how well the European Union is able to defend the Iran nuclear accord following the United States’ withdrawal.
Ties between Tehran and Damascus have been close since the 1979 revolution, but the relationship deepened after Syria’s civil war erupted in 2011. With the Assad regime’s survival at stake, Tehran doubled down on its support, providing critical military assistance—fighters and strategists—and economic aid estimated to be in the hundreds of millions of dollars.
