Dubya reportedly told the Palestinian Prime Minister

God told me to strike at al Qaida and I struck them, and then he instructed me to strike at Saddam, which I did, and now I am determined to solve the problem in the Middle East. If you help me I will act, and if not, the elections will come and I will have to focus on them.

I guess he's just got that old-time religion:

When Ashur, who selected me, who made my kingship great, entrusted his merciless weapon into my lordly arms, I verily struck down the widespread troops of Lullumu with weapons, during the battle encounter. As for the troops of the lands of Nairi, Habhu, Shubaru, and Nirbu, I roared over them like Adad the destroyer, with the aid of Shamash and Adad, my helper gods. [I am] the king who caused [the lands] from the other bank of the Tigris to the Lebanon and the Great Sea, the whole of Laqu, and Suhu as far as Rapiqu, to submit; [who] himself conquered [the territory] from the source of the Subnat River to Urartu; [who] annexed as my own territory [the area] from the pass of Kirruru to Gilzanu, from the other bank of the Lower Zab to Til Bari which is upstream from Zaban, from Til sha Abtani to Til sha Zabdani. I counted as my own people [those who occupy the territory] from the pass of Babite to Hashmar. I set my resident [official]s in the lands over which I ruled [and imposed upon them] obeisance and [forced labor].

That's from a king of Assyria, whose territory included most, if not all, of modern-day Iraq. So that's what was behind the war -- not so much the debatable WMD evidence, nor the promises of democracy which we seem less and less likely to follow through on, just Dubya going back to his roots.

Update: Here, via Gallowglass, is yet another explanation:

Sitchin's thesis of an ancient ET presence in Sumer combined with the notion of a variety of ET transportation devices described by other authors in their research of ancient civilizations, and resumption of archaeological excavations of the first Sumerian capital Uruk in 2002, give support to William Henry's thesis of a Stargate that lies buried in the sands of southern Iraq. This provides important contextual information that is helpful in understanding the true motivations of the Bush administration in launching a preemptive attack on Iraq.

It may be argued that the Bush administration and the Hussein Regime are both in a race against time to gain access and control of the Stargate in the ruins of Uruk or some other location in Iraq, before the prophesied return of the Anunnaki. At the moment, a stalemate exists. Hussein controls the ground in Southern Iraq, and is permitting the German led excavations in Uruk, while the US led coalition controls the sky and is monitoring the situation. The Bush administration wants control of Iraq territory to take control of excavations of Uruk to uncover its buried Stargate, and closely monitor and control it. In contrast, Hussein wants to find and activate the Stargate for his greater glory and presumably the benefit of humanity.

This jibes with the available evidence at least as well as a typical Ari Fleischer press conference
