Let's assume the up-coming negotiations over Iran's nuclear energy program totally breaks down and nothing is agreed to and everybody goes home angry and fed up. Or, as they say in Texas, "All bets are off."
And so Condi and Rummy are given orders by Cheney to get the ball rolling on Operation Iran Secularization.
Accusations that Iran is behind attacks against Americans in Iraq escalate, but this time backed up with "solid evidence": such as photographs, capture of "spies", video confessions, and communication intercepts.
A daring rescue mission by the Marines manages to bring back one of the platoon members. He gives graphic information about the inhumane torture he had endured over the past 48 hours, including having one of his eyes gauged out.
The next day an "Iranian" pilot defects and lands in Baghdad, and it turns out the pilot is accompanied by a high ranking Revolutionary Guard general, and when surrounded by reporters and American Marines, the general declares: "Iran has purchased four nuclear warheads from the Ukraine. And they are fitting them onto their missiles."
While the war drums start to beat louder and louder a report comes in that an Iranian missile has just sunk an unarmed merchant ship in the Persian Gulf and all hands on board are reported to have gone down with the vessel. News leaks that it was a hospital ship, and two hundred female nurses and thirty doctors were among the drowned.
Standing amidst grieving family members waiting to receive the flag draped coffins of their loved ones Bush declares Iran's sinking of the hospital ship an act of war and orders an immediate attack on Iran's naval forces in the Persian Gulf.
Iran denies sinking the ship and provides proof in the form of radar reports showing that Iran had not fired any missile or torpedo. The denial is drowned out as corporate media goes into full scale war frenzy. Ignored by the media is evidence that an Israeli submarine was seen in the vicinity.
America launches an attack on all Iranian naval targets and within 72 hours sinks the entire Iranian navy, and half of the missile batteries hidden along the Iranian coastline. During the next 48 hours Iran's entire air force is destroyed and the following 48 hours all Revolutionary Guard buildings, barracks, and factories get leveled.
Bush declares the entire Iranian airspace a no fly zone. All ports are blockaded. Preparations begin for occupation of Khuzestan province and control of Iran's oil and gas industry. America continues to attack anything military related in Iran but avoids oil and gas installations.
Within the first six hours Iran has cut off all oil shipments out of Iraq. Bombed and disrupted oil outflows from all pipelines heading west from the Caspian Sea, and used short range missiles to stop all oil shipments from Kuwait, plus activated sleeper mines all across the Persian Gulf and the Straights of Hormuz.
During the next 48 hours Iran succeeds in cutting American supply lines from Kuwait, shoots down three aircrafts landing or leaving Baghdad airport with shoulder fired missiles, and rains down missiles onto the Green Zone forcing it to be evacuated.
