President Biden says the U.S. will not remove sanctions on Iran until it complies with the terms of the 2015 nuclear deal. The U.S., under Trump, unilaterally withdrew from the deal in 2018 despite widespread international opposition. Iran has since resumed enriching uranium but maintains its nuclear program is for peaceful purposes. Iran’s Supreme Leader Ayatollah Ali Khamenei says the U.S. must first return to the agreement and has lost its right to set any conditions on the deal’s parties.
