Kingdom of Saudi Arabia has been relatively stable as compared to other countries in the Middle East even though it has maintained the most authoritarian political system in the region. The very two important reasons that kept it stable are as there was no the strong internal power against the Saudi royal family in Saudi Arabia nor the external sponsor to activate the opposition. This situation was from the traditional divide and rule strategy of Saudi Royal family. As the political changes in the region going on since 2011, Al- Sahwa, Liberal, Shiite reformists in Saudi Societies have called the Saudi Royal Family the common Political System Reforms involving ``the Protection of Human Rights, Constitutional Monarchy, Parliamentary Elections``. These reform forces are judging that Saudi political system has reached the critical point of change that can`t be avoided as calling a suitable reform of the political system instead of a revolutionary change of sacrifice myriad. In the last three years, both the effort of Saudi royal family to strengthen the regional hegemony through the military intervention in Syria and the effort to emasculate the opponents to call the political reform failed. In addition, as hoping that the situation in Syria will be resolved with negotiations, the United States is pursuing the negotiations over the nuclear issue with Iran that has built the hostile relationship with Saudi Arabia. If you look the Middle East policy of the United States that has changed, it is possible that U.S. policy of Saudi Arabia turns into the direction to prefer political reform movement. The Saudi royal family has no a special alternative and will seek a compromise with the political reform movements in order to maintain the minimum political power as following the U.S policy. In the result, a new political map that reflects the diverse and pluralistic societies in Saudi Arabia will appear.
