The interim agreement says that as a member of the Nuclear Non-Proliferation Treaty, Iran will at some point be treated as any other non-nuclear weapons NPT member state, if it honors commitments it takes on under a final agreement.
But the big question is when? And what happens then?
The U.S. and its allies will likely seek to extend the agreement for up to 25 years for maximum assurance that Iran has forsworn any potential nuclear weapons ambitions. Samore says Iran wants the final agreement to end after five years, and when it does expire Tehran can start building its nuclear program like any other non-weapon NPT states.
