The modern Middle East has rarely been tranquil, but it has never been this bad. Full-blown civil wars rage in Iraq, Libya, Syria, and Yemen. Nascent conflicts simmer in Egypt, South Sudan, and Turkey. Various forms of spillover from these civil wars threaten the stability of Algeria, Jordan, Lebanon, Saudi Arabia, and Tunisia. Tensions between Iran and Saudi Arabia have risen to new heights, raising the specter of a regionwide religious war. Israel and the Palestinians have experienced a resurgence of low-level violence. Kuwait, Morocco, Oman, Qatar, and the United Arab Emirates have weathered the storm so far, but even they are terrified of what is going on around them. Not since the Mongol invasions of the thirteenth century has the Middle East seen so much chaos.
