It does, however, mandate restrictions on Iran for a limited period of time and mandates the snapback to prevent those restrictions from expiring if Iran misbehaves. The Security Council imposed restrictions on Iran over several years and those restrictions can’t just go away just because eight parties sign some side political agreement. The straight reading of the U.N. Security Council resolution makes it undeniable that the United States has the right to trigger the snapback. The question is whether states will knowingly ignore the text of a binding Security Council resolution and try to ignore the U.S. complaint. Snapback will restore prior Security Council resolutions on Iran so that all the long-term restrictions, like the arms embargo, remain in place indefinitely.
