Bush claimed that Hussein possessed WMDs to justify invading Iraq. After the WMDs never materialized, Bush gave liberating the Iraqi people as his excuse. Later the reason for invading Iraq became to spread democracy across the Middle East.
For some reason, Bush couldn't seem to bring himself to utter the 'O' word. Of all Bush's justifications du jour, none of them included invading Iraq for her oil, even though she sat on the second largest oil reserves on the planet. This was quite unexpected considering Bush was a failed oil man and his VP was a successful CEO in the oil services industry.
Last week, things changed. Bush suddenly became fixated on oil during his press conference in the Rose Garden. It seemed he couldn't stop saying the 'O' word.
In his opening statements, Bush recognized the large oil reserves in Iraq. He said, "We can't tolerate a new terrorist state in the heart of the Middle East, with large oil reserves that could be used to fund its radical ambitions." Of course, he has also made it clear that the USA will be occupying Iraq for the duration of his term in office. Maybe he hopes he can one day use the reserves to fund his radical ambitions.
Later, he claimed that the "ideological caliphate" in Iraq "want to control oil resources." He never explained what interest Moslems "that use religion to achieve objectives" would have in oil. Perhaps Bush was just reflecting his own desire to control oil resources.
Finally, Bush broached the concept of "radical forms" having "the capacity to use oil as an economic weapon." However, the Iraqi petroleum infrastructure is so degraded it cannot even supply Iraq with petroleum products, let alone fund the war in Iraq as originally proposed by the administration. Bush did not elaborate on how this impotent industry in Iraq could be an economic weapon. It could have simply been wishful thinking on Bush's part to use it as an economic weapon himself.
Bush has denied the accusations that he invaded Iraq for her oil for years now. It appears that denying himself for so long left him helpless, after finally allowing himself to speak of oil, from being caught up in the throes of the big 'O.'
