Dick Cheney, Don Rumsfeld, and Paul Wolfowitz wanted to "finish" the 1990s Gulf War by removing Saddam Hussein from power. The post-911 War Against Terrorism was the perfect backdrop to manufacture a false, imminent threat from a fictional weapon of mass destruction.
Not many in Congress had the fortitude to challenge the White House's campaign to expand the War Against Terror to Iraq, especially those Dems looking to run for President in 2004. They were afraid voting against war in Iraq would make them look weak in the War Against Terror.
Bush '43 White House decisions that were strategically inept. Rumsfeld abandoned the Weinberger Doctrine of 9-1 force superiority to send too few, ill-equipped soldiers to deal with the post-invasion Sunni Iraqi insurgence. The post-invasion situation was made worse by the appointment of Paul Bremer as Provisional Coalition Administrator of Iraq.
The pre-invasion "intelligence failure" was willful blindness to any intelligence which weakened the argument of an imminent threat of an Iraqi weapon of mass destruction, used to justify the invasion.
The post-invasion "intelligence failure" was a combination of willful blindness, incompetence, and politically corrupt motives of senior officials in the Bush '43 administration.
The Iraq Invasion of 2003 was a manufactured 2004 Presidential Campaign photo-op to give Bush '43 a military victory like Bush '41.
It was also an opening salvo to the effort to remake the world in America's image. Neo-cons wanted America to liberate the world's peoples to build nations allegedly built upon shared American and Western values.
