One key fault line in the Arab world is the divide between countries ruled by hereditary monarchs —the Emirs, Sultans, and Kings of the region—and those countries that overthrew monarchs or won independence and established republican governments. This is a major factor that divides the government, law, culture and society in the countries of the Arab world.

When Iraq—a socialist republic that overthrew its Hashemite king in the late 1950s—invaded the Persian Gulf Emirate of Kuwait, one justification was the “liberation” of the country from a tyranical monarch. Not surprisingly, the reaction by Arab governments to this invasion was closely linked to its system of government. Consider the following map, together with the map above:

The divide is clearest in the Arabian Peninsula—all the monarchies of the GCC backed fellow charter state Kuwait, while Yemen, which had overthrown its monarch in North Yemen in the 1960s and which had a contentious relationship with the Saudis, backed Saddam. The Palestinian Liberation Organization also voiced support for Saddam (which drastically hurt their international political standing for several years). Libya spoke out against any Arab military action against Iraq, Sudan quietly voiced support for Saddam, while Morocco’s King sent troops to join the coalition forces. Looking at the first map, and seeing the conflict as a republican v.s. monarch war, the allegiances thus far look relatively predictable.
It is only in Egypt, Jordan and Syria that this model is reversed. US ally Egypt and pro-Iranian Syria backed the US coalition. Jordan’s King Hussein decided to voice support for Saddam, either because of general public opinion or because of his refusal to ally with the Saudis against another Arab country, and its US relationship suffered as a result. Meanwhile, Algeria, which was in the process of violent democratic reforms, saw its political elite divided on the subject and never took any official position, while Tunisia, a monarchy republic of the Mediterranean, wanted to stay out of the conflict. (Lebanon barely had a foreign policy at the time and trying to escape its violent civil strife and ipso-facto control by Syria was just coming to an end at this time.)
These fault lines were completely different during the Iran-Iraq War, when two republics were warring with each other. Kuwait, Saudi Arabia, and the UAE (through Abu Dhabi), and most Arab countries backed Iraq, and it was only Syria, Libya, and Sheikh Maktoum of Dubai that backed Iran. But that was when a secular Sunni Arab state was fighting a Shitte Islamist revolutionary republic. Then, the fault lines were different.
