This resolution would allow the President to use military force against Iran if the country seriously violates the nuclear deal, AKA, the Joint Comprehensive Plan of Action (JCPA). Military action would be used to eliminate Iran's nuclear capabilities. This legislation would function the same way as an authorization of force under the War Powers Resolution.
If the President thinks that an Iranian violation of the JCPA seriously threatens U.S. national security, and decides to use military force, he or she must first notify and work with Congress to ensure that:
The International Atomic Energy Agency (IAEA) agrees that Iran has failed to comply with its commitments and obligations under the JCPA;
The United Nations Security Council has re-imposed its sanctions against Iran because the country violated the agreement;
Congress has the plans (both scope and strategy) for using Armed Forces against Iran.
After this resolution’s enactment, the President would send a report to Congress (at least once every 60 days) detailing armed forces activities and redeployment plans. The authority granted by this legislation would end one year after its enactment — meaning that continued military operations against Iran would require a new authorization.
