Despite a purely partisan Republican push to alter the terms of the Iran nuclear deal, an overwhelming majority of US lawmakers from both parties continues to advance legislation to counter Iranian behavior throughout the Middle East.

The House passed four bills today and Wednesday taking aim at Iran’s ballistic missile program and its support for Hezbollah, the Lebanese Shiite paramilitary group fighting alongside Iranian forces on behalf of the Bashar al-Assad regime in Syria. In addition, Iran hawks in Congress continue to press the Donald Trump administration to ban US aircraft sales to Iran and designate the Islamic Revolutionary Guard Corps (IRGC) as a foreign terrorist organization.

"The whole thing with the [nuclear deal] that irked me throughout was that during the course of the negotiations … we were told consistently that this was only about nuclear weapons,” Rep. Eliot Engel, D-N.Y., the top Democrat on the House Foreign Affairs Committee, told Al-Monitor. “We couldn’t raise terrorism, we couldn’t raise ballistic missiles. We couldn’t raise all the other things against Iran and it frustrated me to no end.”

“I think those of us who really feel that Iran is a major cause of instability in the Middle East need to make sure that Iran is sanctioned,” Engel added.
