It is about oil to a point, and that is why the US cannot admit defeat. Oil is flowing out Iraq and it is US companies that are reaping the benefits and dollars, and not the Iraqi people, so to a certain extent the war is going fabulously well.
The War on Terror aspect is completely phoney. Iran has long been the worry in the region since the CIA appointed Shah was overthrown. Iran has been further on than Iraq in the development of Nuclear weapons (though they are still 5-10 years off). Also Washington fears the spread of fundamental Islam because it knows it cannot control it (the usual bribes don't work with religious zealots). This is where Bush No.2 has failed miserably.
Bush 1 supported Iraq in the Iran-Iraq war to stop Iran not because he was enamored with Sadam, and the policy of containing Iran continued with Clinton. Dubya has undermined all that good work. Iran now has influence on large parts of Iraq, and openly flouts its escalating Nuclear programme. And the US are now in an helpless position - out gunned, out manoevered and more worryingly, out thought.
