Iraq is a mess, neighbouring states are using it to play out their power games and the sectarian divide between the Sunni and Shi'ites is being stoked up by gangs, militia, criminals and the “resistance”. Much of the political establishment seems to have been taken over by Shi'ites and many of them seem hell-bent on revenge. If it is bad now, then I dread to think what it will be like once the US and coalition forces withdraw to their bases.
One particular group which faces daily murderous attacks in Iraq are Lesbians and Gays, their plight is detailed at their blog: http://iraqilgbtuk.blogspot.com/
It doesn't bear thinking about what will happen when the Islamists gain unchallenged power in Iraq.
