“A fourth enduring strand of policy has been to help improve the life of man. From the Marshall Plan to this very moment tonight, that policy has rested on the claims of compassion, and the certain knowledge that only a people advancing in expectation will build secure and peaceful lands. This year I propose major new directions in our program of foreign assistance to help those countries who will help themselves. We will conduct a worldwide attack on the problems of hunger and disease and ignorance. We will place the matchless skill and the resources of our own great America, in farming and in fertilizers, at the service of those countries committed to develop a modern agriculture. We will aid those who educate the young in other lands, and we will give children in other continents the same head start that we are trying to give our own children. To advance these ends I will propose the International Education Act of 1966. I will also propose the International Health Act of 1966 to strike at disease by a new effort to bring modern skills and knowledge to the uncared—for, those suffering in the world, and by trying to wipe out smallpox and malaria and control yellow fever over most of the world during this next decade; to help countries trying to control population growth, by increasing our research—and we will earmark funds to help their efforts. In the next year, from our foreign aid sources, we propose to dedicate $1 billion to these efforts, and we call on all who have the means to join us in this work in the world.”

2014, Statement on Cuban policy (December 2014)
Context: I’m under no illusion about the continued barriers to freedom that remain for ordinary Cubans. The United States believes that no Cubans should face harassment or arrest or beatings simply because they’re exercising a universal right to have their voices heard, and we will continue to support civil society there. While Cuba has made reforms to gradually open up its economy, we continue to believe that Cuban workers should be free to form unions, just as their citizens should be free to participate in the political process.
Moreover, given Cuba’s history, I expect it will continue to pursue foreign policies that will at times be sharply at odds with American interests. I do not expect the changes I am announcing today to bring about a transformation of Cuban society overnight. But I am convinced that through a policy of engagement, we can more effectively stand up for our values and help the Cuban people help themselves as they move into the 21st century.
