President Bush is due to give a speech Monday on the war on terror, as his administration opens a campaign to assure Americans there is a strategy for success in Iraq.
Mr. Bush, who will speak in Washington, is expected to give a series of speeches to mark the three-year anniversary of the U.S.-led invasion of Iraq.
Vice President Dick Cheney, Defense Secretary Donald Rumsfeld and Secretary of State Condoleezza Rice will also work to re-state the administration's political, economic and security strategy in the country.
This comes as opinion polls show nearly four of five Americans - and 70 percent of the Republican Party - believe Iraq will disintegrate into civil war. But President Bush said Saturday he is optimistic Iraq will not collapse into civil war.
He said he believes Iraqi leaders recognize that sectarian violence in the country will undermine their ability to self-govern.
Another poll released last week, by Associated Press and Ipsos put Mr. Bush's approval rating at 37 percent, the lowest of his presidency.
