This paper explores the question of adherence to commitments to joint Arab action, particularly in the security realm. The author contends that Arab cooperative frameworks for the combatting of terrorism remain the most relevant and potent force to overcome intra-Arab rivalries of the type which have most recently led a group of four Arab countries to blockade Qatar. The author further contends that piecemeal or separate bi-lateral frameworks, or even multi-lateral agreements between a number of actors—such as were in evidence during the latest Gulf Crisis—will never be a replacement for collective Arab action on these points. Such collective Arab action must be based on foundations of mutual commitment and respect for the sovereignty of the individual countries, incentivizing them to build channels of cooperation.
