There's no way to understand the larger-than-life United States-Iran psychodrama, the Western push for regime change in both Syria and Iran, and the trials and tribulations of the Arab Spring(s) - now mired in perpetual winter - without a close look at the fatal attraction between Washington and the GCC.
GCC stands for Gulf Cooperation Council, the club of six wealthy Persian Gulf monarchies (Saudi Arabia, Qatar, Oman, Kuwait, Bahrain and the United Arab Emirates - UAE), founded in 1981 and which in no time configured as the prime strategic US backyard for the invasions of Afghanistan in 2001 and Iraq in 2003, for the long-drawn battle in the New Great Game in Eurasia, and also as the headquarters for "containing" Iran.
The US Fifth Fleet is stationed in Bahrain and Central Command's forward headquarters is based in Qatar; Centcom polices no less than 27 countries from the Horn of Africa to Central Asia - what the Pentagon until recently defined as "the arc of instability". In sum: the GCC is like a US aircraft carrier in the Gulf magnified to Star Trek proportions.
I prefer to refer to the GCC as the Gulf Counter-revolution Club - due to its sterling performance in suppressing democracy in the Arab world, even before Mohammed Bouazizi set himself on fire in Tunisia over a year ago.
