Bush said the United States has Iraq's best interest in mind as the invasion begins.
"We come to Iraq with respect for its citizens, for their great civilization and for the religious faiths they practice. We have no ambition in Iraq, except to remove a threat and restore control of that country to its own people," he said.
Bush also told Americans that "helping Iraqis achieve a united, stable and free country will require our sustained commitment."
In closing, Bush said, "We will pass through this time of peril and carry on the work of peace. We will defend our freedom. We will bring freedom to others. And we will prevail. May God bless our country and all who defend her."
