The religious right are encouraging the Iraqi war for religious reasons - part of a much larger plan.
Here is Bill Moyer's explanation.
According to this narrative, Jesus will return to earth only when certain conditions are met: when Israel has been established as a state; when Israel then occupies the rest of its “biblical lands;” when the third temple has been rebuilt on the site now occupied by the Dome of the Rock and Al-Aqsa mosques; and, then, when legions of the Antichrist attack Israel. This will trigger a final showdown in the valley of Armageddon during which all the Jews who have not converted will be burned. Then the Messiah returns to earth. The Rapture occurs once the big battle begins. True believers” will be lifted out of their clothes and transported to heaven where, seated next to the right hand of God, they will watch their political and religious opponents suffer plagues of boils, sores, locusts and frogs during the several years of tribulation which follow.
I’m not making this up. We’re reported on these people for our weekly broadcast on PBS, following some of them from Texas to the West Bank. They are sincere, serious, and polite as they tell you that they feel called to help bring the Rapture on as fulfillment of biblical prophecy. That’s why they have declared solidarity with Israel and the Jewish settlements and backed up their support with money and volunteers. It’s why they have staged confrontations at the old temple site in Jerusalem. It’s why the invasion of Iraq for them was a warm-up act, predicted in the 9th chapter of the Book of Revelations where four angels “which are bound in the great river Euphrates will be released “to slay the third part of men.’ As the British writer George Monbiot has pointed out, for these people the Middle East is not a foreign policy issue, it’s a biblical scenario, a matter of personal belief. A war with Islam in the Middle East is not something to be feared but welcomed; if there’s a conflagration there, they come out winners on the far side of tribulation, inside the pearly gates, in celestial splendor, supping on ambrosia to the accompaniment of harps plucked by angels.
One estimate puts these people at about 15% of the electorate. Most are likely to vote Republican; they are part of the core of George W. Bush’s base support. He knows who they are and what they want. When the President asked Ariel Sharon to pull his tanks out of Jenin in 2002, over one hundred thousand angry Christian fundamentalists barraged the White House with emails and Mr. Bush never mentioned the matter again. Not coincidentally, the administration recently put itself solidly behind Ariel Sharon’s expansions of settlements on the West Banks. In George Monbiot’s analysis, the President stands to lose fewer votes by encouraging Israeli expansion into the West Bank than he stands to lose by restraining it. “He would be mad to listen to these people, but he would also be mad not to.” No wonder Karl Rove walks around the West Wing whistling “Onward Christian Soldiers.” He knows how many votes he is likely to get from these pious folk who believe that the Rapture Index now stands at 144 --- just one point below the critical threshold at which point the prophecy is fulfilled, the whole thing blows, the sky is filled with floating naked bodies, and the true believers wind up at the right hand of God. With no regret for those left behind. (See George Monbiot. The Guardian, April 20th, 2004.)
