It's not appealing to deal with countries that express hatred towards us.

What I want to try to do is unify the two wings of the Democratic Party. What's considered the more progressive wing of the Democratic Party - the more centrist wing of the party. I think we can craft an approach that is more American, pro-worker, pro-business, pro-growth.

My job is to communicate to the American people that the Muslim world is filled with extraordinary people who simply want to live their lives and see their children live better lives. My job to the Muslim world is to communicate that the Americans are not your enemy. We sometimes make mistakes. But if you look at the track record America was not born as a colonial power, and that the same respect and partnership that America had with the Muslim world as recently as 20 or 30 years ago, there's no reason why we can't restore that. And that I think is going to be an important task.
