Washington: President George W. Bush took the blame on Wednesday for going to war in Iraq over faulty intelligence but said he was right to topple Saddam Hussain and urged Americans to be patient as Iraqis vote.

"It is true that much of the intelligence turned out to be wrong. As president I am responsible for the decision to go into Iraq, and I am also responsible for fixing what went wrong by reforming our intelligence capabilities and we're doing just that," he said.

But he said, "My decision to remove Saddam Hussain was the right decision" because he was deemed a threat and that regardless, "We are in Iraq today because our goal has always been more than the removal of a brutal dictator."

Bush's Iraq comments came in the last of a series of four speeches outlining his Iraq strategy and trying to bolster American support for the war, came a day ahead of an Iraqi election that will pave the way for formation of a permanent government.

His administration touted Iraqi weapons of mass destruction as a reason for going to war in March 2003, but such weapons were never found.

In what some political analysts have perceived to be a move by Bush to talk more frankly on the US difficulties in Iraq, Bush also admitted to "tactical mistakes" in an interview with Fox News.

In his interview, Bush gave strong endorsements to Defense Secretary Donald Rumsfeld and Vice President Dick Cheney, both frequently accused by critics of pushing the war on false pretenses.

Bush asked for patience from Americans to give Iraqis time to form their new government after the election. After the vote, he said, there will be "days of uncertainty" and the winners may not be clear until the early part of January.

He reiterated his dismissal of Democratic calls for a phased US pullout and accused Democrats who charge him with manipulating prewar intelligence of playing politics.

"He's done a heck of a job," Bush said of Rumsfeld, "and I have no intention of changing him." As for Cheney, "my respect for him has grown immensely," Bush said.

The president said in his speech that Sunni Arabs, who have fueled the bloody insurgency, were increasingly abandoning violence to take part in their Iraq's politics and would turn out in large numbers Thursday after boycotting January elections.

The US president, who embraced preemptive war as US strategy after the September 11, 2001 terrorist attacks, did not name any potential targets, but said the Iraq vote would put pressure on the governments of Iran and Syria.

"We are living through a watershed moment in the story of freedom," he said. Iraq "will be a model for the Middle East. Freedom in Iraq will inspire reformers from Damascus to Tehran."
