A quote from the book:
The justification for invading Iraq was due to the following five reasons “attributed to three senior advisers (Cheney, Rumsfeld, and Wolfowitz) and to President Bush:
•To clean up the mess left by the first Bush administration when, in 1991, it let Saddam Hussein consolidate power and slaughter opponents after the first U.S. – Iraq war;
•To improve Israel’s strategic position by eliminating a large hostile military;
•To create an Arab democracy that could serve as a model to other friendly Arab states now threatened with internal dissent, notably Egypt and Saudi Arabia;
•To permit withdrawal of U.S. forces from Saudi Arabia (after twelve years), where they were stationed to counter the Iraqi military and were a source of anti-Americanism threatening to the regime;
•To create another friendly source of oil for the U.S. market and reduce dependency upon oil from Saudi Arabia, which might suffer overthrow someday.”
