ALI JUMA, IRAQ - JUNE 12: US forces of 3rd Platoon, Bronco Troop, 1st Squadron, 14th Cavalry, conduct a village during a clearance operation lead by Iraqi Kurdish forces, on June 12, 2010, in Ali Juma, Iraq. Iraq faces multiple challenges in the lead-up to the drawn-down of US forces in Iraq, with reports claiming while they are capable of handling home-grown problems, but are a long way off being able to tackle external threats. Political wrangling has reportedly fostered greater instability throughout the country with fears of renewed sectarian violence breaking out as insurgents set-up attacks in an attempt to exploit vulnerabilities amongst the populace.
