Context: In short, both the United States and its allies, and the Soviet Union and its allies, have a mutually deep interest in a just and genuine peace and in halting the arms race. Agreements to this end are in the interests of the Soviet Union as well as ours — and even the most hostile nations can be relied upon to accept and keep those treaty obligations, and only those treaty obligations, which are in their own interest. So, let us not be blind to our differences — but let us also direct attention to our common interests and to the means by which those differences can be resolved. And if we cannot end now our differences, at least we can help make the world safe for diversity. For, in the final analysis, our most basic common link is that we all inhabit this small planet. We all breathe the same air. We all cherish our children's future. And we are all mortal.

Context: In many ways we have the young people, we have the talent, we have the imagination, we have the technology. But I don't believe we have the leadership and the willingness to accept risk, to achieve great goals. I believe we need a long-term national commitment to explore the universe. And I believe this is an essential investment in the future of our nation — and our beautiful, but environmentally challenged planet.
