The 1962 coup d'etat in North Yemen initiated one of the most debilitating Middle East conflicts ever, the eight-year civil war in North Yemen. This conflict in an obscure corner of the Arab world eventually assumed global importance, attracting the attention of the superpowers and the United Nations. This book focuses on the Yemeni civil war’s impact at the regional level, where it provoked enmity between two influential Arab states, Saudi Arabia and Egypt. Dr. Badeeb argues that for Egypt, the war constituted a means of intensifying and confirming its role as the leader of the revolutionary camp in the Arab world. For Saudi Arabia, however, it presented a direct challenge to the security and stability of the kingdom. Dr. Badeeb provides a valuable elucidation of Saudi Arabia’s concern over Yemen as a potential source of political and strategic upheaval. This lately unappreciated aspect of the regional security picture is in part a legacy of the Saudi-Egyptian conflict of the 1960s and is one of the central elements of current Saudi security policy.
