It's a very long story, you need to have a backgroud about the two countries in which the Syrian regime is an absolute dictatorship while the Bahraini which is a constitutional monarchy afford their citizens with everything. We Arabs were always make jokes about Syrian regime brutality before the uprising. But in short:
Syrian protesters had been peaceful for the first six months inspired by Egyptian, Yemenis and Tunisians peaceful uprisings although the regime mass killed thousands using heavy weapons, brutally tortured thousands and refused to meet any of their demands. While in Bahrain they chant "peaceful" but they used swords, guns, Molotov to attack police in the very first days of "uprising" instigated and supported by Iran. You can check YT videos regarding my claims. Syrian regime used everything to obliterate whole cities including Scud missiles while in Bahrain used tear gas and hot water except for few cases when the police used guns and those were punished and the deceased families were given compensations. Pls, Bahraini get free high quality health care, education, houses, high salaries, jobs, subsidy and free to join political parties. While in Syria people live the worst lives in the ME. There is nothing to compare.
.....
you forgot that Iraq was part of GCC and we have always stood side by side in all arab causes
