Prior to the invasion, while it was common to accuse opponents of providing objective, if not intentional, support to Saddam, none of the major antiwar organizations declared any support for him, however limited. After the invasion and the toppling of Saddam's regime, some who had opposed it now supported continuing U.S. occupation, arguing that the U.S.'s intervention had given it an obligation to stabilize the country. However, those who remained opposed to the U.S. presence had to determine their approach to the developing armed insurgency and peaceful opposition to the occupation carried out by groups like the Worker-Communist Party of Iraq (WCPI).
