General David Petraeus has taken charge of U.S. forces in Iraq, becoming the third commander in the war. He said the American task is now to help Iraqis “save the country.”

Gen. Petraeus: “The challenges ahead are substantial. The rucksack of responsibility is very heavy. In truth, it is too heavy for any one person to bear, and we will all have to share the burdens and move forward together. And if we can do that, and if we can help the people of Iraq do likewise, then the prospects for success are good. Failing that, Iraq will be doomed to continuing violent and civil strife, and surely that is a prospect that all must strive to avoid.”
