There are three major components of the Iraqi insurgency: nationalist guerrillas, Shiite militants and jihadists. Those with the greatest military impact on the coalition war effort are the nationalist guerrillas, which are largely Sunni-led insurgents that include former members of the Iraqi army and others from all segments of Iraqi society. However, the Shiite militants exert the strongest political pull and will do the most to determine how long U.S. troops stay in Iraq. Jihadists will continue to make life difficult for coalition troops, but their numbers are few and their power to shape events relatively weak. When former Iraqi President Saddam Hussein was captured Dec. 13, 2003, STRATFOR suggested the nationalist guerrillas slowly would lose their heart for the fight and ultimately become little more than a nuisance.
