Seven people are killed and 41 injured today in a massive explosion at a Baghdad hotel. This week marks the one-year anniversary of the U.S. invasion of Iraq. With more than 100,000 American troops still on the ground, the battle there continues.

One year ago, President Bush promised “to disarm Iraq, to free its people and to defend the world from grave danger.” It took three weeks to oust Saddam Hussein. As Bush said in his State of the Union address, today “the people of Iraq are free.” Yet more than 550 U.S. troops and 3,000 Iraqis have been killed. Many more have been wounded. And the fighting there continues. Tonight, On Point, judging the war in Iraq.
