They have set an August 31st deadline for Iran to resume negotiations with the U.S., allow full access for IAEA inspectors at nuclear sites as well as account for more than 400 kilograms of highly enriched uranium that has gone undetected – something Britain, France and Germany seem determined to do just this week. Iran has responded to these developments with threats of severe consequences should snapback sanctions be reinstated. They include suspending all cooperation with the International Atomic Energy Agency (IAEA) and withdrawing from the Nuclear Non-Proliferation Treaty (NPT), according to reports from Reuters, PressTV and The Washington Post. After withdrawing from the JCPOA in 2018, the United States continues to support E3’s efforts to hold Iran accountable. Secretary Rubio noted the necessity of taking an international approach against Iran’s nuclear ambitions and regional activities; reiterating U.S. commitments not to develop nuclear weapons while keeping pressure on Tehran to comply with international norms and norms (pressTV). As August 31 approaches, the international community remains on high alert, closely watching Iran’s response and any ramifications it might have on regional and global security. Diplomatic efforts could significantly alter Iran’s nuclear program as well as relations between Tehran and Western countries.
