On the one-year anniversary of the U.S. withdrawal from the Iran nuclear deal, President Trump issued an executive order imposing sanctions on Iran’s iron, steel, aluminum, and copper industries, ratcheting up what he calls a “maximum pressure” campaign against the rogue regime.

Noting that Iran gains significant revenue through metal exports, the order states that it is U.S. policy to deny the Iranian government funds that “may be used to provide funding and support for the proliferation of weapons of mass destruction, terrorist groups and networks, campaigns of regional aggression, and military expansion.”
