Under the nuclear deal, U.S. will maintain all sanctions against Iran's terrorist proxies and IRGC

The United States will also maintain powerful sanctions targeting Iran’s support for terrorist groups such as Hizballah and its sponsors in Iran’s Islamic Revolutionary Guard Corps–Quds Force; its destabilizing support to the Houthis in Yemen; its backing of Assad’s brutal regime; its missile program; and its human rights abuses at home. Just this week, Treasury sanctioned several Hizballah leaders, building on designations last month that targeted the group’s front companies and facilitators. We will not be providing any sanctions relief to any of these lines of activity and will not be delisting from sanctions the IRGC, the Quds Force, or any of their subsidiaries or senior officials.

I also want to emphasize that secondary sanctions imposed by Congress will continue to attach to these designations, providing additional deterrence internationally. For example, a foreign bank that conducts or facilitates a significant financial transaction with Iran’s Mahan Air or Bank Saderat will risk losing its access to the U.S. financial system. These sanctions will continue to be in place and enforced; they are not covered by the JCPOA.
