“Let’s all pull together and make these United States the grandest place in this whole country.”

Introduction, p. xxv
The Age of Fallibility (2006)
Context: We must recognize that as the dominant power in the world we have a special responsibility. In addition to protecting our national interests, we must take the leadership in protecting the common interests of humanity. I go into some detail as to what that entails.
Mankind’s power over nature has increased cumulatively while its ability to govern itself has not kept pace. There is no other country that can take the place of the United States in the foreseeable future. If the United States fails to provide the right kind of leadership our civilization may destroy itself. That is the unpleasant reality that confronts us.

AP report with lead summarizing of remarks stating "Robert F. Kennedy said yesterday that the United States — despite Alabama violence — is moving so fast in race relations a Negro could be President in 40 years." "Negro President in 40 Years?" in Montreal Gazette (27 May 1961) http://news.google.com/newspapers?nid=1946&dat=19610527&id=y40tAAAAIBAJ&sjid=F50FAAAAIBAJ&pg=5424,5208719
Context: The Irish were not wanted there [when his grandfather came to Boston]. Now an Irish Catholic is president of the United States … There is no question about it. In the next 40 years a Negro can achieve the same position that my brother has. … We have tried to make progress and we are making progress … we are not going to accept the status quo. … The United States Government has taken steps to make sure that the constitution of the United States applies to all individuals.

1990s, Inaugural celebration address (1994)
Context: We are both humbled and elevated by the honour and privilege that you, the people of South Africa, have bestowed on us, as the first President of a united, democratic, non-racial and non-sexist government.
We understand it still that there is no easy road to freedom
We know it well that none of us acting alone can achieve success.
We must therefore act together as a united people, for national reconciliation, for nation building, for the birth of a new world.
Let there be justice for all.
Let there be peace for all.
