There's no doubt that when it comes to our treatment of Native Americans as well as other persons of color in this country, we've got some very sad and difficult things to account for. I personally would want to see our tragic history, or the tragic elements of our history, acknowledged. I consistently believe that when it comes to whether it's Native Americans or African-American issues or reparations, the most important thing for the U.S. government to do is not just offer words, but offer deeds.

We are in what we hope is an intensive diplomatic phase now. It will not be open-ended.

Let's remember that our leadership is defined not just by our defence against threats, but by the enormous opportunities to do good and promote understanding.

Did I recognize that there was anger or frustration in the American population? Of course I did. First of all, we had to fight back from the worst recession since the Great Depression, and I can guarantee you if your housing values have crashed and you've lost most of your pension and you've lost your job, you're going to be pretty angry.

By some estimates, the oil you recently discovered off the shores of Brazil could amount to twice the reserves we have in the United States. We want to work with you. We want to help with technology and support to develop these oil reserves safely, and when you're ready to start selling, we want to be one of your best customers.

This is the moment when we must come together to save this planet.
