A series of bomb blasts have ripped through Baghdad and surrounding towns on the 10th anniversary of the U.S.-led invasion that began a decade-long war in Iraq. At least 56 people died in more than a dozen explosions, most of them car bombings. It was 10 years ago today that the United States, under President George W. Bush, invaded Iraq on the false pretext that Saddam Hussein was hiding weapons of mass destruction. Now, a decade after the invasion began, a new poll confirms most people in the United States believe it was a mistake.
