Iraq recovered its full sovereignty at the end of 2011, with the departure of all US military forces. The 2003 invasion was undertaken to dismantle a regime that had long threatened its own population and regional peace, as well as to establish a stable, democratic state in the heart of the Middle East. This Adelphi looks at the legacy of that intervention and subsequent state-building efforts. It analyses the evolution of the insurgency, the descent into full-scale civil war and the implementation of the 'surge' as a counterinsurgency strategy. It goes on to examine US and Iraqi efforts to reconstruct the state's military and civilian capacity.

Will Iraq continue on a democratic path, as exemplified by the three competitive national elections held since 2005? And does the new Iraq pose a threat to its neighbours? s held since 2005? And does the new Iraq pose a threat to its neighbours?.
