The IAEA has consistently for the past six found Iran non-compliant for inspection and removal of materials from sites. It was bound by the conditions of a really flawed JCPOA that permitted Iran to collect soil samples and handle them before turning them over and not being permitted to enter military sites where nuclear materials were handled so already over half of the suspected sites were even included in the JCPOA. It's worth noting that the framework for the JCPOA was taken from the previous North Korea agreement and we see how that turned out.
