This is a half-truth itself. The 24 days rule applies to military facilities. All nuclear sites, like Natanz, Arak, Bushehr, Esfahan etc. are under 24/7 surveillance, and they have all been redesigned to make nuclear weapons development impossible.
The argument given is that even within 24 days, it would be impossible to remove any trace of a military nuclear program. In any case, any connection between nuclear and military facilities could not simply be covered up this easily; whether this is the case or not, the fact that international inspectors would be given access to a nation's military facilities is a major concession in itself. Just imagine an Iranian inspector asking for access to an American military base. It's a clear sign that Iran is not yet an equal partner in the "deal"/treaty, and they signed it nevertheless.
"Some experts say that’s sufficient to detect violations, while others disagree." I am not a nuclear scientist .. so I really do not know.
.. again just by virtue of it having been signed, that was probably reason enough to stick with it .. unless there was a serious violation by Iran. Due to relations with Europe if anything. But I am not convinced it was a good deal to start with.. the sanctions being much more gradually listed over time based on compliance would have been a better route .. and on a related note, that is how things should go with N. Korea if a some kind of deal comes out of the upcoming meetings.
Both countries put themselves out of the international norm ... and need to earn their way back in.
