It's not that difficult to understand. From CNNMoney.com (emphasis in red; I’ve taken out the links in the original):
“With the war in Iraq now estimated to cost the United States nearly $2 trillion over the next ten years, many taxpayers are probably wondering what happened to all that oil money that was supposed to help pay for the war.”
“. . . Iraq is currently lucky to pump 2 million barrels a day. Decades of war and neglect have nearly halved production from a high of 3.5 million barrels in the late 1970s. Output is now below where it was when the United States first invaded in 2003, and some experts say that Iraq could see production fall by 200,000 barrels a day per year under present conditions.
Proceeds from Iraq's current oil sales - about $30 billion a year in 2006 - go to funding the Iraqi government. In fact, the Iraqi government is nearly entirely dependent upon oil for its funding, with crude accounting for at least 90 percent of its budget.
Boosting oil production seems to be in everyone's interest. Iraq would get more money, and the U.S. may have to pony up a little less for reconstruction. Total U.S. spending in the country, on both military and reconstruction, has now topped $368 billion through 2007, according to the Congressional Budget Office.”
“Currently all of the country's 2 million barrels a day are pumped by the national oil company.
A smattering of small foreign firms have signed contracts to pump oil in the country, mostly in the semi-autonomous Kurdish region in the north. But until pipelines stop blowing up and a stable national government is in place, the big western firms like Exxon Mobil (Charts, Fortune 500), BP (Charts), Royal Dutch Shell (Charts) and Chevron (Charts, Fortune 500) - and the big money they could spend on exploration and infrastructure - will stay away.
‘You would need a very stable, long-term legal environment’ for the big western oil companies to invest the tens of billion of dollars needed to really ramp up production there, said Greg Priddy, a global energy analyst at the Eurasia group, a political risk consultancy. ‘Everyone sees this as a long-term opportunity, but they have to get the political situation sorted out first.’”
International Jewry requires their minion Americans to stay in Iraq, ‘surging’, until the country is broken up into the three parts required by the Zionist Plan for the Middle East. On the other hand, the political situation in Iraq can never be stabilized for Western oil interests until the Americans leave. Thus, not only could the war never have been about oil, the grim logic of Zionism dictates that the United States will have to continue to operate in exactly the opposite way than the oil companies would have required for them to be able to even start to exploit the oil in Iraq. It isn’t just an unfortunate accident that Western oil companies can’t get at the oil: the entire attack was predicated on following the Zionist goal of weakening an enemy of Israel by breaking it up, and that goal is logically inconsistent with Western oil exploitation, and has been since the Zionists first planned the attack.
