Krugman:

To understand what’s really happening in Iraq, follow the oil money, which already knows that the surge has failed.

Back in January, announcing his plan to send more troops to Iraq, President Bush declared that “America will hold the Iraqi government to the benchmarks it has announced.”

Near the top of his list was the promise that “to give every Iraqi citizen a stake in the country’s economy, Iraq will pass legislation to share oil revenues among all Iraqis.”

There was a reason he placed such importance on oil: oil is pretty much the only thing Iraq has going for it. Two-thirds of Iraq’s G.D.P. and almost all its government revenue come from the oil sector. Without an agreed system for sharing oil revenues, there is no Iraq, just a collection of armed gangs fighting for control of resources.

Well, the legislation Mr. Bush promised never materialized, and on Wednesday attempts to arrive at a compromise oil law collapsed.

What’s particularly revealing is the cause of the breakdown. Last month the provincial government in Kurdistan, defying the central government, passed its own oil law; last week a Kurdish Web site announced that the provincial government had signed a production-sharing deal with the Hunt Oil Company of Dallas, and that seems to have been the last straw.

Now here’s the thing: Ray L. Hunt, the chief executive and president of Hunt Oil, is a close political ally of Mr. Bush. More than that, Mr. Hunt is a member of the President’s Foreign Intelligence Advisory Board, a key oversight body.

Some commentators have expressed surprise at the fact that a businessman with very close ties to the White House is undermining U.S. policy. But that isn’t all that surprising, given this administration’s history. Remember, Halliburton was still signing business deals with Iran years after Mr. Bush declared Iran a member of the “axis of evil.”
