The Bush Regime lumps all factions that are anti-American as terrorists, evil killers, evil doers. It's simpler that way. Al Q in Iraq number maybe around 1K. Various Insurgency factions are not all Sunnis and number around 25K. Various factions have different goals.
Iraqi Insurgency
In January 2005 Iraqi intelligence service director General Mohamed Abdullah Shahwani said that Iraq's insurgency consited of at least 40,000 hardcore fighters, out of a total of more than 200,000 part-time fighters and volunteers who provide intelligence, logistics and shelter. Shahwani said the resistance enjoyed wide backing in the Sunni provinces of Baghdad, Babel, Salahuddin, Diyala, Nineveh and Tamim. Shahwani said the Baath, with a core fighting strength of more than 20,000, had split into three factions.
The main one, still owing allegiance to jailed dictator Saddam Hussein, is operating out of Syria. It is led by Saddam's half-brother Sabawi Ibrahim al-Hassan and former aide Mohamed Yunis al-Ahmed, who provide funding to their connections in Mosul, Samarra, Baquba, Kirkuk and Tikrit. Izzat Ibrahim al-Duri is still in Iraq. Two other factions have broken from Saddam, but have yet to mount any attacks. Islamist factions range from Abu Musab al-Zarqawi's al-Qaeda affiliate to Ansar al-Sunna and Ansar al-Islam.
A picture of the composition of the insurgency, though in constant flux, has come into somewhat greater focus. London-based International Institute for Strategic Studies estimates roughly 1,000 foreign Islamic jihadists have joined the insurgency. And there is no doubt many of these have had a dramatic effect on perceptions of the insurgency through high-profile video-taped kidnappings and beheadings. However, American officials believe that the greatest obstacles to stability are the native insurgents that predominate in the Sunni triangle. Significantly, many secular Sunni leaders were being surpassed in influence by Sunni militants. This development mirrors the rise of militant Shia cleric and militia leader Moqtada al-Sadr vis-à-vis the more moderate Shia cleric Grand Ayatollah al-Sistani.
