Middle East expert Juan Cole analyzes the military prospects in Iraq

[...]

The guerrillas have widespread popular support in the Sunni Arab areas of Iraq, an area with some 4 million persons. Its cities and deserts offer plenty of cover for an unconventional war. Guerrilla movements can succeed if more than 40 percent of the local population supports them. While the guerrillas are a small proportion of Iraqis, they are very popular in the Sunni Arab areas. If you look at it as a regional war, they probably have 80 percent support in their region.

The guerrillas are mainly Iraqi Sunnis with an intelligence or military background, who know where secret weapons depots are containing some 250,000 tons of missing munitions, and who know how to use military strategy and tactics to good effect. They are well-funded and can easily get further funding from Gulf millionnaires any time they like.

The Iraqi guerrillas are given tactical support by foreign jihadi fighters. There are probably only a few hundred of them, but they are disproportionately willing to undertake very dangerous attacks, and to volunteer as suicide bombers.

There are simply too few US troops to fight the guerrillas. There are only about 70,000 US fighting troops in Iraq, they don't have that much person-power superiority over the guerrillas. There are only 10,000 US troops for all of Anbar province, a center of the guerrilla movement with a population of 820,000. A high Iraqi official estimated that there are 40,000 active guerrillas and another 80,000 close supporters of them. The only real explanation for the successes of the guerrillas is that the US military has been consistently underestimating their numbers and abilities. There is no prospect of increasing the number of US troops in Iraq.

The guerillas have enormous advantages, of knowing the local clans and terrain and urban quarters, of knowing Arabic, and of being local Muslims who are sympathetic figures for other Muslims. American audiences often forget that the US troops in Iraq are mostly clueless about what is going on around them, and do not have the knowledge base or skills to conduct effective counter-insurgency. Moreover, as foreign, largely Christian occupiers of an Arab, Muslim, country, they are widely disliked and mistrusted outside Kurdistan.

So far the new pro-American Iraqi troops have not distinguished themselves against the guerrillas, and it will probably be at least 3-5 years before they can begin doing so, if ever. Insofar as the new army is disproportionately Shiite and Kurdish, it may simply never have the resources to penetrate the Sunni Arab center-north effectively. There is every reason to believe that the new Iraqi military is heavily infiltrated with sympathizers of the guerrillas.

US military tactics, of replying to attacks with massive force, have alienated ever more Sunni Arabs as time has gone on.

AP reports an Iraqi official saying today that there is a civil war going on in the northern city of Telafar between Sunnis and Shiites.

In an ideal world, the United States would relinquish Iraq to a United Nations military command, and the world would pony up the troops needed to establish order in the country in return for Iraqi good will in post-war contract bids. But that is not going to happen for many reasons. George W. Bush is a stubborn man and Iraq is his project, and he is not going to give up on it. And, by now the rest of the world knows what would await its troops in Iraq, and political leaders are not so stupid as to send their troops into a meat grinder.

The guerrilla war is likely to go on a decade to 15 years. Given the basic facts, of capable, trained and numerous guerrillas, public support for them from Sunnis, access to funding and munitions, increasing civil turmoil, and a relatively small and culturally poorly equipped US military force opposing them, led by a poorly informed and strategically clueless commander-in-chief who has made himself internationally unpopular, there is no near-term solution.
