Iran is vowing to take drastic measures if this new resolution allows the International Atomic Energy Agency (IAEA) to access two controversial sites that they’ve restricted to date; Iran blames Israel as the source of this investigation.

In what is an unexpected scenario, the United Nations is considering a resolution that has been put forth by several European countries to have the International Atomic Energy Agency (IAEA) investigate two sites in Iran. Tehran is rejecting this idea and has already voiced that there will be repercussions should the IAEA move forward with their investigation.

Should the IAEA move forward, they would be investigating these two particular sites for nuclear activity; specifically, nuclear activity that would further prove that Iran has for some time been in violation of the Joint Comprehensive Plan of Action (JCPOA), or Iran Nuclear Deal, put forth in 2015. Iran, thus far, has restricted the IAEA from entering these sites.

Iran’s UN ambassador in Vienna, Kazem Gharib Abadi, responded to the resolution stating, “Introduction of this resolution aiming to call on Iran to cooperate with the Agency… is disappointing and absolutely counterproductive.”

He would further warn on Tuesday, should the resolution pass, “Iran would have no choice but to take appropriate measures, the consequences of which would be upon the sponsors of such political and destructive approaches.”

The IAEA is calling on Iran to simply comply. If you have nothing to hide, why not? They also cited “some commercial satellite imageries that contained no convincing underlying reason,” as a motive for their investigation.

In an odd, but not surprising retaliation, Iran is already citing Israel as the source of this investigation. While Israel certainly has done their fair share of recon on the Islamic Republic’s nuclear activity, it’s fair to say that they don’t have a close relationship with the UN. The IAEA has also taken other actions against Tehran that had nothing to do with the Jewish State.

This is the first time the UN has considered a resolution that is critical of Tehran since 2012.
