We all have to learn to live together.

I have said many times-if I hadn't been exposed to music as a child I don't think I would have been president.

But the truth is, countries have to do what is best in each instance to pursue both their interest and their values.

I think it's crazy for us to play games with our children's future. We know what's happening to the climate, we have a highly predictable set of consequences if we continue to pour greenhouse gases into the atmosphere.

I know that the precise magnitude and patterns of climate change cannot be fully predicted. But global warming clearly is a growing, long-term threat with profound consequences. And make no mistake about it, it will take decades to reverse.

I don't like to use the word sacrifice.

We should not let our response to the people who disagree with us be dictated by what they say about us or even how they treat people we care for. There has to be a chance that we can find love.
