An article from the Washington Institute on 17th September says that Washington should co-ordinate its designations with Baghdad to avoid upsetting the government formation process or throwing Iran a lifeline. It says that on September 19th, the US House of Representatives will introduce the “Iranian Proxies Terrorist Sanctions Act,” which calls for imposing US sanctions on 2 Iranian-controlled Iraqi militias – Asaib Ahl al-Haq (AAH) and Harakat Hezbollah al-Nujaba (HHN). If passed, the legislation will also require the State Department to maintain a public list of armed groups funded, controlled, or influenced by Iran’s Islamic Revolutionary Guard Corps. The draft Bill follows a White House warning to Tehran about reining in its proxy militias after successive rocket attacks on US diplomatic facilities in Iraq. The author makes recommendations, including the comment that sanctioning AAH and HHN is legally justified, but the timing and sequencing of any such move is critical to maximising the desired effects and minimizing Iran’s ability to exploit Iraqi backlash. If the Iranian Proxies Terrorist Sanctions Act becomes law, the Trump Administration should carefully calibrate the manner in which militias and individuals are sanctioned under it, closely coordinating US efforts with the next Iraqi government.
