Some ideas never die. Most recently, the Trump administration, reportedly via a phone call from National Security Advisor John Bolton to Egypt’s acting head of intelligence, Abbas Kamel, proposed the creation of an Arab expeditionary force to be deployed to Syria. In the process, the White House was resurrecting a concept that, for decades, has surfaced periodically in Middle Eastern discourse only to quickly evaporate and then suddenly re-emerge. The idea of a regional military alliance that can represent collective Arab political and security interests in conflicts dates back to at least the 1950s. But the political will to facilitate its creation has never been sufficient to get past the suggestion phase, and it is unlikely to suddenly emerge now, despite U.S. pressure and the dire straits in which the concept of a collective “Arab national interest” finds itself.
