US oil companies will get no privileged access to Iraqi oil. They probably could, as China just did, sign contracts to service Iraq’s oil industry, but they won’t get control or any share of the profits.
There will be no permanent US military bases in Iraq to intimidate Iraq and its neighbors and enforce profit-sharing control of any mideast oil, at a time when North and South American oil is drying up fast.
Now, the most obvious result of the invasion of Iraq:

Iran’s mortal enemy, the Baathist Sunnis led by Saddam Hussein, have been vanquished and effectively eliminated.
Iran’s blood relatives, the Shiites of Iraq, have now been installed as the unchallenged rulers of the government of Iraq in Baghdad and over most of Iraq, extending Iran’s influence exponentially.
The US military, reserves and national guard have been decimated and weakened for decades.
The US economy has been bankrupted and paralyzed.
You’d think Iran might have planned the whole adventure and sent a team of persuasive misinformation artists, say, call them the Iraqi National Congress, across Europe and the US, led by an accomplished pathological liar, like, say, Ahmed Chalabi, to play on the ignorance, arrogance and global strategies of the rulers of America, say maybe the neocons and their Program for a New American Century, to convince them they would get cheap acces to Iraqi oil and permanent military bases, and be welcomed as liberators, and to provide a package of propaganda stories, say, about WMDs, ties to bin Laden, etc., to convince the American public that invading Iraq was required and would be easy.
When will the mainstream blogosphere catch up to the this news behind the news?
