Flynn is a supporter of current Israeli policies. He is also an opponent of the Iran nuclear deal. In February 2017, Flynn said "the Obama administration failed to respond adequately to Tehran's malign actions—including weapons transfers, support for terrorism and other violations of international norms". Flynn accused Yemen's Houthi rebels of being one of Iran's "proxy terrorist groups" in February 2017. Flynn also criticized Obama's administration for arming Syrian rebels linked to Salafi jihadism. According to Flynn, the U.S. is "at war with a radical component of Islam". Flynn has been a board member of ACT! for America, and sees the Muslim faith as one of the root causes of Islamist terrorism.
