Con to the question "Should the US Have Attacked Iraq?"
"In the last three years, the United States of America suffered the two worst intelligence failures in its history. The Iraq War and the September 11 attacks on the World Trade Center and the Pentagon cost thousands of lives, hundreds of billions of dollars and fundamentally changed US relations with the rest of the world.
The two reports from the US Senate Committee on Intelligence and the 9/11 Commission show that both were preventable. Wiser policies, wiser leaders and wiser choices would have shown the war in Iraq to be unnecessary and could likely have blocked al Qaeda's airplane hijackings."
