US will not sign nuclear deal without inspections of sites, scientists

"If we don’t get the assurances we need on the access to possible military dimension-related sites or activities, that’s going to be a problem for us," State Department spokeswoman Marie Harf said in Washington Wednesday. "We and Iran have agreed that we will undertake a process to address possible military dimensions (of past nuclear work), and part of that includes access," Harf said. "Under the Additional Protocol … which Iran will implement and has said they will implement as part of this deal, the IAEA does get access."

“If we cannot agree in the final instance to something that meets our bottom line for what we need in terms of access, we’re not going to sign a final deal. And that’s just something we’ve been very, very clear about,” she added.
