The governments of the Gulf Cooperation Council (GCC) are heeding the call to reform . Low oil prices have shaken their economies — even the economies that have diversified away from energy production — and the threat of unrest looms large. In each of the six countries that make up the bloc, enacting reform will be an uphill battle. But some Gulf governments, and their people, will have an easier time than others. For leaders in Saudi Arabia , Bahrain and, to a lesser extent, Kuwait, change will entail immediate and difficult choices to prioritize policies and decide who will bear the brunt of cutbacks. The heads of Qatar and the United Arab Emirates, by contrast, have the luxury of time on their sides.
