If this is true, Bush deserves to be impeached:
Ex-CIA Official Faults Use of Data on Iraq
The former CIA official who coordinated U.S. intelligence on the Middle East until last year has accused the Bush administration of "cherry-picking" intelligence on Iraq to justify a decision it had already reached to go to war, and of ignoring warnings that the country could easily fall into violence and chaos after an invasion to overthrow Saddam Hussein.
Paul R. Pillar, who was the national intelligence officer for the Near East and South Asia from 2000 to 2005, acknowledges the U.S. intelligence agencies' mistakes in concluding that Hussein's government possessed weapons of mass destruction. But he said those misjudgments did not drive the administration's decision to invade.
"Official intelligence on Iraqi weapons programs was flawed, but even with its flaws, it was not what led to the war," Pillar wrote in the upcoming issue of the journal Foreign Affairs. Instead, he asserted, the administration "went to war without requesting -- and evidently without being influenced by -- any strategic-level intelligence assessments on any aspect of Iraq."
"It has become clear that official intelligence was not relied on in making even the most significant national security decisions, that intelligence was misused publicly to justify decisions already made, that damaging ill will developed between [Bush] policymakers and intelligence officers, and that the intelligence community's own work was politicized," Pillar wrote.
Pillar's critique is one of the most severe indictments of White House actions by a former Bush official since Richard C. Clarke, a former National Security Council staff member, went public with his criticism of the administration's handling of the Sept. 11, 2001, attacks and its failure to deal with the terrorist threat beforehand.
Bush and company will, of course, deny these allegations and the Republican Congress is not about to investigate them, so I doubt anything will come of it. But if you want to know why Democrats are so angry (along with other people who are paying attention) then here it is in a nutshell.
