Will the US agree to a new Iranian nuclear deal before August?

An agreement also made with other countries (i.e. multilaterally) is still encompassed if the United States participates. "A new Iran-US nuclear deal" means a formal written agreement signed by authorized representatives of both the United States and Iran that (1) imposes verifiable restrictions on Iran's nuclear program, including limits on uranium enrichment, centrifuge numbers, or nuclear facility operations, AND (2) provides for the lifting, suspension, or modification of at least one US economic sanction on Iran in exchange for Iran's nuclear commitments.
