From May 13-16, President Donald J. Trump will repeat the opening gesture of his first administration by making the initial major diplomatic travel of his second term to Saudi Arabia (excluding his unanticipated visit to Rome for the funeral of the late Pope Francis) but this time also including the United Arab Emirates and Qatar. This trip comes at a highly significant moment in U.S.-Gulf Arab relations, and all parties will have specific agendas and deliverables at stake. Overall, Trump’s trip reinforces the centrality of these partnerships for all sides and signals that he continues to view Gulf Arab countries as important partners, not just for the United States but for his personal and political goals.
