The US statement to the IAEA BOG on Iran's safeguards is out. Looks like the US will support the E3 resolution & says its "a balanced and fair reaction" to Iran's refusal to cooperate with the IAEA's investigation into undeclared nuclear materials & sites https://vienna.usmission.gov/iaea-bog-u-s-on-npt-safeguards-agreement-in-iran/

A resolution from the IAEA Board calling on Iran to cooperate with agency is an appropriate response at this time, as Iran's refusal to cooperate with the IAEA's investigation over the past year undermines the safeguards regime, nonproliferation norms, & Tehran's credibility.

While it is very concerning that Iran appears to have violated its safeguards agreement by failing to declare materials and activities from the pre-2003 period, the activities in question do not pose a new threat or increase the proliferation risk posed by the current program.

It is critical that the Trump administration does not politicize the resolution and use it as an excuse to continue its campaign to collapse the #IranDeal. If anything, the IAEA's investigation underscores the necessity of full implementation of the JCPOA by all parties.

Given Iran’s past illicit nuclear activities, the intrusive monitoring and stringent limits put in place by the JCPOA provide a critical bulwark against a future nuclear weapons program and provide important tools for the IAEA to investigate allegations of undeclared activities.
