I've seen a lot of commentaries on this issue on DU so apologies if it's passe to some. However, the rationale that underpins US military adventurism makes little sense given the political fallout worldwide. WTF go into Iraq at huge human and monetary cost and wreck relations with other nations as a consequence?
There are a number of answers to that question, many of which have validity, in varying degrees. But it's worth asking the question again and again. Some people cite oil supply per se but it's not quite that simple it seems.
For example, factor in the rhetoric directed at "rogue" nations which have a lot of oil such as Iran; Iran does not use dollars for oil as far as I am aware.
There is a mass of information floating around on this issue but how many times have you seen it discussed by the MSM?

According to research by Dr. David Spiro, in 1974 the Nixon administration negotiated assurances from Saudi Arabia to price oil in dollars only, and invest their surplus oil proceeds in U.S. Treasury Bills. In return the U.S. would protect the Saudi regime. According to his book, The Hidden Hand of American Hegemony: Petrodollar Recycling and International Markets <18>, these purchases were done in relative secrecy. These agreements created the phenomenon known as "petrodollar recycling." In effect, global oil consumption via OPEC provides a healthy subsidy to the U.S. economy. Hence, the Europeans created the euro to compete with the dollar as an alternative international reserve currency. Obviously the E.U. would also like oil priced in euros as well, as this would reduce or eliminate their currency risk for oil purchases.

It would appear that any attempt by OPEC member states in the Middle East or Latin America to transition to the euro as their oil transaction currency standard shall be met with either overt U.S. military actions or covert U.S. intelligence agency interventions. Under the guise of the perpetual `war on terror' the Bush administration is manipulating the American people about the unspoken but very real macroeconomic reasons for this upcoming war with Iraq. This war in Iraq will not be based on any threat from Saddam's old WMD program, or from terrorism. This war will be over the global currency of oil. A war intended to prevent oil from being priced in euros.
