Here’s a reassuring little tidbit of information; United Nations nuclear inspectors are only allowed to visit Iranian facilities that have been declared by Iran as nuclear sites: Diplomats: U.N. Lacks Right to Inspect Sites in Iran.

VIENNA (Reuters) - Inspectors from the U.N. nuclear watchdog would like to visit a military complex in Iran that an exile group said housed a nuclear weapons site, but they lack the legal authority to go there, U.N. diplomats said.

Iran, which insists its nuclear program is solely for electricity generation, earlier this week escaped possible U.N. Security Council economic sanctions after agreeing to freeze all activities which could be used to make bomb-grade material.

But several military sites inspectors would like to inspect are legally off-limits to the International Atomic Energy Agency (IAEA), which only has clear rights to visit facilities declared to it as nuclear sites. Access to other facilities must be negotiated and can be highly problematic.
