Since the Iranian Revolution in 1978, Iran has been the leading state sponsor of terrorism. Working through the Quds Force, a unit that conducts, among others, covert intelligence gathering and special operations around the world, the Iranian government has been assisting Hezbollah in Lebanon, Shia militias in Iraq and Syria, the Houthi rebels in Yemen, and Hamas in Gaza. The Quds Force, which is part of the Iranian Revolutionary Guard Corps (IRGC), has been financing, advising, training, or leading the above terrorist groups (Hezbollah, alone, has been getting $700 million per year).

Now, the Trump administration has announced its new strategy to counter Iranian-backed terrorism. In a recent interview, Nathan A. Sales, the U.S. Ambassador-at-Large and Coordinator for Counterterrorism, stated that the U.S. government will continue to sanction individuals and organisations in the Iranian terrorism-chain.

Over 150 Hezbollah-affiliated entities and individuals have been financially sanctioned. Moreover, last year, in an unprecedented move, the U.S. government labelled the IRGC as a Special Designated Global Terrorist. The State Department, further, designated more Hezbollah and Hamas leaders as terrorists.
