Bush2 and his neo-con cabal keeps telling us what a disaster it would be if the US withdrew from Iraq. These so-called" risks" are easily refuted with the cold water of common sense from Barry R. Posen, director of the Security Studies Program at the Massachusetts Institute of Technology, on the "risks" of U.S. withdrawal from Iraq....
Al Qaeda will take over the country. This risk is now non existent. Al Qaeda's support is strongest among Sunnis, whom the Shia outnumber by three to one. The Shia control the military, the police, and numerous militias. The United States has ramped up its operations in Baghdad in part to stop the Shia from cleansing the Sunnis from Baghdad. There will be no caliphate in Baghdad, whether Americans stay or leave.
Iraq will become a new Afghanistan, to Al Qaeda's benefit. The most extreme among the Sunni insurgents may indeed be committed to international jihad, and they may continue to work clandestinely out of Iraq, as they do today. But these jihadis will not be comfortable. Iraqi Shi'ites despise them, and even many Sunnis oppose them. US intelligence will indeed have to keep an eye on them, and special operations forces may occasionally need to sneak back into Iraq to strike at them. These are capabilities the United States has spent billions building up since Sept. 11.
The current civil war (or wars) will escalate. Fighting may indeed intensify after a US disengagement. To come to an understanding of how wealth and power in Iraq will be shared, the political forces there must measure their relative capacity and will. The United States now stands in the way of such a measurement, and the US presence delegitimizes any outcome. The promise of a certain US withdrawal date may clear the heads of some Iraqi politicians ; a negotiated settlement could start to look better to them than an escalation of fighting.
Genocide. The humanitarian consequences of this intensified fighting could be grave. But genocide happens against unarmed populations; all groups in Iraq are heavily armed. Still, the violent ejection of minorities from particular areas is likely. Instead of convincing minorities to stay in neighborhoods where they are vulnerable to murder by local majorities, the United States can help people resettle in parts of Iraq that are safer.
If the civil war intensifies, regional powers will rush in. This too is already under way, but escalation into a giant civil war is not in anyone's interest. Syria, Iran, and Turkey have Kurdish minorities which may become restive during such a war. The Saudis would likely prefer that their Sunni Arab friends make a deal, rather than wage a fight that they might lose. Even Iran, whose Shia co-religionists stand to win such a war, faces risks. The Arab Shia are not one big happy family; they kill each other in Iraq today. Most Iraqi Shia think of themselves as Arabs; heavy-handed Iranian intervention may energize their nationalist opposition.
The worst case. The civil war escalates; outsiders back their friends; their friends begin to lose, so the war escalates to become a regional conflagration. Could happen, but one should not exaggerate the military capabilities of any of the local players. They are all heavily armed, but conventional warfare is not the strong suit of any of the regional actors, with perhaps the exception of Turkey. The Saudi forces, though equipped with modern weapons, are almost surely helpless without help from western contractors. Iran's air forces are obsolete and highly vulnerable to American air attack. Moreover, Saudi Arabia and Iran are one-crop countries; each depends on oil facilities that are vulnerable to attack by the other. A kind of Mutual Assured Destruction should deter both from risking general war.
Compare the "risk" of US withdrawal from Iraq with the COST of maintaining the occupation:
WASHINGTON - The Pentagon is spending more than $5.8 billion a month on the war in Iraq, according to the military's top generals. That is nearly a 50 percent increase above the $4 billion-a-month benchmark the Pentagon has used to estimate the cost of the war so far. Iraq War Topping $5.8 Billion a Month / UPI Nov 19, 04
Obviously, the cost is not worth the risk.
