This thesis examines Middle Eastern security issues and problems which are rooted to geographical considerations or determinants. Geography as a security policy determinant is also examined on a national level in selected countries which are the primary regional actors: Egypt, Saudi Arabia, Israel, Syria, and Iraq. A substantial portion of the work is naturally oriented toward the Arab-Israeli territorial disputes. It is not, however, restricted to that theme. Demographic and strategic communications problems, completely separate from the Arab-Israeli issues, are also explored. (Author)
