2014, Statement on Cuban policy (December 2014)
Context: Today, the United States of America is changing its relationship with the people of Cuba.
In the most significant changes in our policy in more than fifty years, we will end an outdated approach that, for decades, has failed to advance our interests, and instead we will begin to normalize relations between our two countries. Through these changes, we intend to create more opportunities for the American and Cuban people, and begin a new chapter among the nations of the Americas.

2015, State of the Union Address (January 2015)
Context: You know, just over a decade ago, I gave a speech in Boston where I said there wasn’t a liberal America or a conservative America; a black America or a white America -- but a United States of America.



Context: There is not a liberal America and a conservative America — there is the United States of America. There is not a Black America and a White America and Latino America and Asian America — there's the United States of America.
