Goodbye from the world's biggest polluter.

Their sacrifice was great, but not in vain. All Americans and every free nation on earth can trace their liberty to the white markers of places like Arlington National Cemetery. And may God keep us ever grateful.

I talked to my little brother, Jeb - I haven't told this to many people. But he's the governor of - I shouldn't call him my little brother - my brother, Jeb, the great Governor of Texas.

The U.S. liberated Iraq from a tyrant. I think the Iraqi people owe the American people a huge debt of gratitude, and I believe most Iraqis express that. I mean, the people understand that we've endured great sacrifice to help them. That's the problem here in America. They wonder whether or not there is a gratitude level that's significant enough in Iraq.

We know that the African regimes, many African regimes have failed their people and many Africans want regime change, and there are a lot of African leaders who make promises but don't carry them out. I mean, the progress - I mean, it is noble for the rich countries to help Africa, but then the question is: What are African leaders themselves doing to help their own people?

I think it's very important for the American president to mean what he says. That's why I understand that the enemy could misread what I say. That's why I try to be as clearly as I can.

I was very fortunate to have had a mother and father who loved me in spite of my failings.
