Oil is the motive
Google "Stephen Pelletiere" and see his video speech in
Bonaventure University 23rd January 2003, 2 parts (http://www.informationclearinghouse.info/article2097.htm). It seems Pelletiere had a
crystal ball of Powell's lies a week later and what Americans will face in Iraq.
As a CIA's Kurd expert in Iraq–Iran
war, he states that the Kurds were gassed in an act of war, not genocide, and
the gas used was Iranian (this conclusion was made by American intelligence in
1988). Both sides used gas in the war against each other. Later the Kurd gassing
story was deliberately changed and it was part of the fabrication of both POTUS
Bushes prior to Iraq wars.
Gassing of Kurds took place in 1988. Pelletiere wrote the New
York Times article In January 2003. He was worried about the unjustified coming
war carefully planned for years by Bush administration's war hawks. 
"I am in a position to know because, as the Central
Intelligence Agency's senior political analyst on Iraq during the Iran–Iraq
war, and as a professor at the Army War College from 1988 to 2000, I was
privy to much of the classified material that flowed through Washington
having to do with the Persian Gulf."
Pelletiere's speech at Bonaventure University, New York, January 27 2003, is
worth listening. Here is my abstract of the speech. 
"The control of oil is the game that America is playing
in the Gulf. Control not possession is the objective. America does not need
to possess Iraq’s oil. However, it must have control over how much oil that
country will produce. At the same time America is going into Iraq to gain
control of Opec.
Britain is the most forward of any country in backing
American invasion in Iraq. When in 1972 the present ruler of Iraq Saddam
Hussein nationalized Iraq’s oil it was Britain, which primarily suffered as
the two British companies British Petroleum and Royal Dutch Shell were
ousted in the takeover. I think it is a fair assumption that Britain counts
on its oil companies reacquiring their former possessions in the event of an
American takeover of Iraq.
France and Germany very much fear that should the United
States invade it would turn all of the Gulf, not the regimes but the
citizenry, against America and after that we will see an escalation of
terrorist attacks. In other words France and Germany foresee that an
American takeover will in a long run do more harm than good.
The so-called Wolfowitz doctrine worked out by the US
Assistance Secretary of Defense Paul Wolfowitz envisions the United States
running a lot more of these preemptive strikes such as this one against Iraq.
In Wolfowitz’s vision the United States will go after Iran next, and then
The war is about oil. However, it is not the case that
America wants to physically process Iraq’s oil so that it can sell it. It is
rather that America feels it must have influence over Iraq’s oil production.
Only by having that can we be sure of regulating prices and only by
regulating prices can we be certain of keeping world economy on an even keel.
Other reasons for invading Iraq are preemptive protection
of Israel and the water resources of Iraq."
