I will just post the wonderful explanation of Iraq war origins written by Republican congressman Ron Paul.
First, why we can exchange paper for real goods:
In the short run, the issuer of a fiat reserve currency can accrue great economic benefits. In the long run, it poses a threat to the country issuing the world currency. In this case thats the United States. As long as foreign countries take our dollars in return for real goods, we come out ahead. This is a benefit many in Congress fail to recognize, as they bash China for maintaining a positive trade balance with us. But this leads to a loss of manufacturing jobs to overseas markets, as we become more dependent on others and less self-sufficient. Foreign countries accumulate our dollars due to their high savings rates, and graciously loan them back to us at low interest rates to finance our excessive consumption.
It sounds like a great deal for everyone, except the time will come when our dollars– due to their depreciation– will be received less enthusiastically or even be rejected by foreign countries. That could create a whole new ballgame and force us to pay a price for living beyond our means and our production. The shift in sentiment regarding the dollar has already started, but the worst is yet to come.
The agreement with OPEC in the 1970s to price oil in dollars has provided tremendous artificial strength to the dollar as the preeminent reserve currency. This has created a universal demand for the dollar, and soaks up the huge number of new dollars generated each year. Last year alone M3 increased over $700 billion.
The artificial demand for our dollar, along with our military might, places us in the unique position to rule the world without productive work or savings, and without limits on consumer spending or deficits. The problem is, it cant last.
Now to the origins of the war:
In November 2000 Saddam Hussein demanded Euros for his oil. His arrogance was a threat to the dollar; his lack of any military might was never a threat. At the first cabinet meeting with the new administration in 2001, as reported by Treasury Secretary Paul ONeill, the major topic was how we would get rid of Saddam Hussein– though there was no evidence whatsoever he posed a threat to us. This deep concern for Saddam Hussein surprised and shocked ONeill.
It now is common knowledge that the immediate reaction of the administration after 9/11 revolved around how they could connect Saddam Hussein to the attacks, to justify an invasion and overthrow of his government. Even with no evidence of any connection to 9/11, or evidence of weapons of mass destruction, public and congressional support was generated through distortions and flat out misrepresentation of the facts to justify overthrowing Saddam Hussein.
And the happy end:
There was no public talk of removing Saddam Hussein because of his attack on the integrity of the dollar as a reserve currency by selling oil in Euros. Many believe this was the real reason for our obsession with Iraq. I doubt it was the only reason, but it may well have played a significant role in our motivation to wage war. Within a very short period after the military victory, all Iraqi oil sales were carried out in dollars. The Euro was abandoned.
I can't say it better.
