Excellent analysis by Ali Khedery in Foreign Affairs on conflicting ethno-sectarian agendas and Iraq’s descend into chaos since 2003:
“Shortly after the invasion, Machiavellian politicians pressed U.S. officials to disband the Iraqi army as they hijacked the U.S.-instituted De-Baathification Commission and used it to extort or purge their secular political opponents, Sunni and Shiite alike. Hundreds of thousands were left permanently unemployed, embittered, and primed to seek violent retribution against the new order.
In the mountainous north, Kurdish leaders sought to consolidate the considerable gains they had achieved through self-governance following the introduction of a no-fly zone in 1991. After a vicious civil war in the mid-1990s, they established the semiautonomous Kurdistan Region, securing peace and attracting foreign investment. Once Saddam was gone, they maintained control of key positions in Baghdad under a new ethno-sectarian quota system as a hedge against further repression.
In the south, the Shiite Islamist parties that had battled Saddam’s secular Baath Party for decades, often with Iran’s covert support, emerged victorious and sought to compensate for past repression. They asserted their will as the majority by defying the Baath’s taboos and establishing numerous official religious holidays, cementing their brand of religious values in the national school curriculum, and placing members of the armed wings of their religious political parties on government payrolls. In the halls of power in Baghdad, the word of Grand Ayatollah Ali al-Sistani, the highest authority in Shiite Islam, reigned supreme.
Iraq’s minority Sunnis, the nation’s ruling elite for centuries, found themselves in disarray. To correct perceived injustices, they eventually settled on a strategy of boycotting democracy in favor of insurgency and terrorism. Hopelessly divided and lacking leadership and vision, Sunni Arabs often fell into the trap of battling the U.S. military occupation and the surging influence of their historical arch-nemesis, Shiite Persian Iran, by striking a deal with the devil: al Qaeda.
So began an endless cycle of killing among militant radicals of all stripes, from remnants of the Baath Party to al Qaeda in Iraq to the Iranian-backed Shiite militias. With each religiously charged atrocity, the Iraqi national identity grew weaker, and the millennia-old senses of self—tribal, ethnic, and religious—grew stronger.”
