Saudi Arabia and Iran have often behaved as serious rivals for influence in the Middle East and especially the Gulf area
since at least Iran’s 1979 Islamic Revolution. While both nations define themselves as Islamic, the differences between their foreign policies could hardly be more dramatic. Recently, the rivalry between Riyadh and Tehran has intensified and been reflected in their policies involving a number of regional states including Iraq, Lebanon, Syria, Egypt, Yemen, Bahrain, and others.
