Bush prohibited democrates to "rewrite history" of war in Iraq
US President George Bush has said too much is at stake in Iraq for politicians to make "false charges" about the reasons for going to war. Amid new questions in Congress about the intelligence used to justify the invasion, he said it was "irresponsible to rewrite history".
He told US veterans Iraq was now the central front in the "war on terror" and the US would prevail.
"Some Democrats and anti-war critics are now claiming we manipulated the intelligence and misled the American people about why we went to war," he said.
"The stakes in the global war on terror are too high and the national interest is too important for politicians to throw out false charges."
More than 100 Democrats in Congress, he argued, had viewed the same intelligence about WMD and had voted to back military action.
Democrats are pushing for an investigation into why WMD were never found in Iraq despite intelligence claims before the war.
An opinion poll suggests less than half Americans support his foreign policy - only 42% approve of his handling of foreign policy and terrorism. 57% of Americans do not think the administration has high ethical standards and do not think Mr Bush is honest. The survey of 1,000 adults has a margin of sampling error of plus or minus 3%.
