DUBAI, United Arab Emirates ⁠— In an angry speech on state television, Iranian President Hassan Rouhani lashed out at the U.S. and Europe for its presence in the Middle East and for what he described as the latter's failures in upholding the 2015 Iranian nuclear deal. U.S. troops are "insecure" in the region today, and EU troops "might be in danger tomorrow," Rouhani declared, according to a Reuters translation, marking the first time the leader has directed a threat toward European forces in the region. He demanded the U.S. leave and accused it of making the region insecure, saying it should "apologize to Tehran" for its "previous crimes." The U.S. has significantly increased its troops presence in the Gulf in the past year as shipping and oil facilities have come under fire from attacks blamed on Iran, which Tehran denies. The U.K. has about 400 forces in Iraq, spread around Irbil, Baghdad and Taji, all locations that have been targeted by Iraqi Shiite militias backed by Iran's Quds Force, the external operations wing of the Islamic Revolutionary Guard Corps. EU forces are also stationed in the Gulf Cooperation Council (GCC) countries, and France and Britain have small numbers of special forces in Syria. A number of EU countries have personnel in Operation Inherent Resolve, the anti-IS coalition, stationed in Iraq. Former Quds Force commander Qasem Soleimani was killed in a U.S. drone strike on Jan. 3, the most dramatic escalation between Washington and Tehran in a series of tit-for-tat attacks. Western forces and embassies in the region have been on high alert since then.
