IRAN (NBC) – The Iran nuclear deal is now formally in effect.
Compliance could eventually provide the country relief from international sanctions.
The deal opens the way for Iran to make major changes to an underground nuclear facility, a heavy water reactor and a site for enriching uranium.
The changes will not happen immediately, and Iran must further rein in its nuclear program before relief from sanctions will occur.
President Obama is expressing confidence that U.S. national security will benefit from the agreement.
