War and Peace
This, my friends, is how the peace will really be lost. Whether or not Chalabi is the titular head of the government or the power behind the throne is probably of small consequence; either way, it's the direct equivalent of, say, installing the Shah on the throne of Iran or helping Pinochet overthrow Allende in Chile. Or supporting Somoza, Marcos, Suharto, the Saud family, etc., etc. You can even make an analogy to supporting a previous ruler of Iraq in his war against the Mullahs who overthrew the Shah.

Here's a prediction: If Chalabi and his cronies gain power, they will be overthrown, perhaps peaceably, more likely violently, within a decade. Their overthrow will be accomplished by rebels who will be, among other things, violently anti-American. The resulting chaos will, once again, undermine any efforts to stabilize the Middle East and bring Islam into the 21st Century.

We haven't learned a damn thing in the last 50 years.
