The execution of Saddam Hussein will not make the United States safer and will only increase the violence in Iraq, the Rev. Jesse Jackson said Sunday. "Killing him intensifies the violence, reduces our moral authority in the world," said Jackson, who has traveled to the Middle East on peace missions. "Today we are not more secure. We're less secure. We've missed a moment to appeal to those in Iraq to break the cycle of violence." The deposed Iraqi leader was hanged Saturday, three years after being captured. He was buried Sunday, and there was no immediate sign of a feared Sunni Muslim uprising in retaliation for the execution, although outside the Sunni insurgent stronghold of Ramadi loyalists marched with Saddam pictures and waved Iraqi flags.
