April 2, 2020 - ISW Press Iran continues to escalate proxy attacks against the U.S. in Iraq, demonstrating that it remains undeterred despite the January 3 strike that killed IRGC - Quds Force Commander Qassem Soleimani and key Iraqi proxy leader Abu Mehdi al-Muhandis and subsequent U.S. strikes. Iran’s proxy network in Iraq is advancing its campaign to compel an American withdrawal by increasing the operational tempo of its attacks on U.S. and allied personnel. Iran’s proxies are responsible for at least 15 attacks on American and U.S.-led Coalition personnel since January 3. A new militia group, Usbat al-Thairen, claimed several recent attacks, indicating that the proxy network may be reorganizing in observance of the shared vision of Soleimani and Muhandis and that Iran may have reached a new phase in its campaign to expel U.S. forces form Iraq.
