Steve was among the greatest of American innovators - brave enough to think differently, bold enough to believe he could change the world, and talented enough to do it...The world has lost a visionary. And there may be no greater tribute to Steve's success than the fact that much of the world learned of his passing on a device he invented.

What is required of us now is a new era of responsibility - a recognition, on the part of every American, that we have duties to ourselves, our nation, and the world, duties that we do not grudgingly accept but rather seize gladly, firm in the knowledge that there is nothing so satisfying to the spirit, so defining of our character, than giving our all to a difficult task. This is the price and the promise of citizenship.

Certainly I've appreciated Angela Merkel as a partner.

Part of people's concern is just the sense that around the world the old order isn't holding and we're not quite yet to where we need to be in terms of a new order that's based on a different set of principles, that's based on a sense of common humanity, that's based on economies that work for all people.

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.

And let me say this as a politician I can promise you this, political leaders will never take risks if the people do not push them to take some risks. You must create the change that you want to see.

John Kerry believes in an America where hard work is rewarded.
