As Mark Twain said, "'If you don't read the newspaper, you're uninformed. If you read the newspaper, you're mis-informed." The media in this country has been creating so much of the news over the past 50 - 60 years we don't even recognize when we are being lied to until well after the fact, if then. Walter Cronkite convinced the American public that we lost the Tet Offensive and that all was lost in SE Asia. The Viet Cong leadership was amazed at that analysis.
CNN and Obama convinced the American public that the Honduras army had staged a coup, when in fact they had defended their constitution by preventing Zelaya from seizing a third term.
The Iraqi people for the most part thought of the US Military as an occupying force and did not give them the open arms treatment Bush and others would have you believe. If you are naive enough to believe there were no WMDs you need to talk to a few Kurds (who are our closest allies in the region in spite of how we keep turning our backs on them). When our troops pulled out the Iraqis started bringing WMDs to Baghdad to be disarmed. British troops were brought in for that task.
It is my belief that the main reason we invaded Iraq (other than being the strong arm of the UN) was to establish a military base there to protect our interest in the area. That didn't happen, and unless Iraq is directly threatened by Iran I don't think it will.
