The coalition fighting against Yemen's Houthi rebels has long been comprised of a wide array of forces, each with their own goals, intentions and prerogatives. The numerous Yemeni actors fighting under the umbrella of the Gulf Cooperation Council (GCC) coalition share a common cause, but that shared cause won't last forever. Once the fight against the Houthis ends, competing loyalties will take priority and new conflicts will arise in Yemen. Recently, a couple of issues have highlighted the underlying tensions within the coalition that threaten to keep Yemen in conflict long after the Houthis are defeated. The Southern Transitional Council (STC) issued a statement blaming the internationally recognized government controlled by President Abd Rabboh Mansour Hadi and the Muslim Brotherhood-affiliated al-Islah party for tension in Aden. More importantly, the statement vaguely alluded to a conflict to be fought after the fight against the Houthis is won.
