It is now generally accepted that the Iraq War came about as a result in large part of manipulation of intelligence, which skewed the decision-making process. Ahmed Chalabi, the multi-millionaire confidence trickster who headed the Iraqi National Congress, fed fabricated information to his neoconservative allies in the Pentagon and White House. The so-called intelligence was repackaged in Doug Feith’s Office of Special Plans (OSP) and stove-piped up to the decision makers, thereby circumventing the normal checks and balances in place at the Central Intelligence Agency for the vetting of raw information. Alleged “reliable sources” provided detailed descriptions of drones capable of flying across the Atlantic Ocean, links with al-Qaeda, chemical and biological stockpiles, and hidden nuclear weapons programs, all of which became the menu du jour for policymakers. Garbage in, garbage out developed into the standard operating procedure as the United States government willy-nilly began a war of aggression against an enemy that presented no threat, Washington’s complete ignorance of facts on the ground best exemplified by its post-invasion futile search for weapons of mass destruction that did not exist.

Less well known is the role played by private neoconservative organizations in cooking the books to make the case for war. In 2001, the United States spent more than $20 billion per year on intelligence gathering and analysis, but the White House still felt it desirable to bring in outside advisers to provide additional insights. President George W. Bush wasregularly briefed by “experts” from the American Enterprise Institute and other neocon think tanks, some of whom were simultaneously working at Feith’s OSP while also writing articles for publications including the Weekly Standard and The Wall Street Journal to make the case for war. It was a perfect trifecta: forge the intelligence, exploit access to the media, and brief a befuddled president based on your own contrived narrative.

In an essentially broken system where any bit of information appeared to be as relevant and reliable as any other bit, it was inevitable that everyone would soon wind up developing his or her own sources. Pentagon number two Paul Wolfowitz, often described as the architect of the Iraq War, was not slow to rise to the bait. In late 2002 and early 2003, Wolfowitz regularly met secretly with a group of Iraqi expatriates, consisting mostly of Shias but also including several Sunnis, who resided in the Washington area and were opponents of the Saddam Hussein regime. The Iraqis had not been in their country of birth for many years but they claimed to have regular contact with well-informed family members and political allies, an assertion not unlike that made by Chalabi. The Iraqi advisers provided Wolfowitz with a now-familiar refrain, i.e. that the Iraqi people would rise up to support invading Americans and overthrow the hated Saddam. They would greet their liberators with bouquets of flowers and shouts of joy.

We also know here on this site (YD) that Challabi was paid by the CIA to fabricate the FAKE intelligent for the CIA. As well:

Note from double crossed:

A while after the beginning of the "war", Challabi was "tainted" by the CIA on false charges of fake currency dealing AND for "divulging sensitive information" to Iran (telling their codes had been broken by US intelligence —the Iranians knew that anyway but played along). In fact I believe the CIA was grooming him to become palatable in the eyes of the Shiite Iraqis so he could be elected to the Iraqi parliament and secretly carry on working for the US. The interesting factor here is that Challabi was tainted "TWICE" in order to reinforce his "liberation" from the exposed CIA clutches. To me it was a cheap trick. Sure, one needs more than one destructive aspect for a destructive attempt to be really successful. Striking from two directions at once, or in quick succession, is the way extinction works... Challabi's CIA's past was thus erased...
