Would 'sunset' of nuclear deal end restrictions on Iran?
The Nuclear Non-Proliferation Treaty would restrain Iran's actions in several ways after the terms of a prospective nuclear deal expire.
Fans and foes of the nuclear talks with Iran are offering sharply divergent views of what the not-so-distant future will look like.
To hear the Obama administration tell it, once Iran submits to rigid restrictions on its nuclear program for a decade or more, the country will still end up confined to a legal straitjacket.
"Iran is forever forbidden from building a nuclear weapon," Secretary of State John Kerry told lawmakers at a Feb. 25 hearing. "That is the nature of membership in the Non-Proliferation Treaty which they are a member of."
Critics counter that the international nonproliferation architecture looks more like a loose shirt baggy enough to conceal a nuclear warhead.
