The author Phillip Weiss says:
Here are my two cents. We invaded Iraq because a powerful group of pro-Israel ideologues — the neoconservatives — who had mustered forces in Washington over the previous two decades and at last had come into the White House were able to sell a vision of transforming the Middle East that was pure wishful hokum but that they believed: that if Arab countries were converted by force into democracies, the people would embrace the change and would also accept Israel as a great neighbor. It’s a variation on a neocolonialist theory that pro-Israel ideologues have believed going back to the 1940s: that Palestinians would accept a Jewish state if you got rid of their corrupt leadership and allowed the people to share in Israel’s modern economic miracle.
The evidence for this causation is at every hand.
It is in the Clean Break plan written for Israeli Prime Minister Netanyahu in 1996 by leading neocons Richard Perle, Douglas Feith and David Wurmser — all of whom would go into the Bush administration — calling for the removal of Saddam Hussein and the export of the Palestinian political problem to Jordan.
It is in the Project for a New American Century letters written to Clinton in 1998 telling him that Saddam’s WMD were a threat to Israel. (A letter surely regretted by Francis Fukuyama, who later accused the neocons of seeing everything through a pro-Israel lens.)
