"President Bush said to all of us: 'I am driven with a mission from God'. God would tell me, 'George go and fight these terrorists in Afghanistan'. And I did. And then God would tell me 'George, go and end the tyranny in Iraq'. And I did."

Mr Bush went on: "And now, again, I feel God's words coming to me, 'Go get the Palestinians their state and get the Israelis their security, and get peace in the Middle East'. And, by God, I'm gonna do it."

Mr Bush, who became a born-again Christian at 40, is one of the most overtly religious leaders to occupy the White House, a fact which brings him much support in middle America.
