PETER KOENIG—Most sanctions on Iran were lifted at the start of 2016 under the nuclear deal, which is enshrined in a U.N. Security Council resolution. The resolution still subjects Tehran to a U.N. arms embargo and other restrictions that are technically not part of the nuclear deal.
Haley has said the Security Council could strengthen the provisions in that resolution or adopt a new resolution banning Iran from all activities related to ballistic missiles. To pass, a resolution needs nine votes in favor, and no vetoes by the United States, Britain, France, China or Russia.
