We've achieved this historic progress through diplomacy, without resorting to another war in the Middle East. I want to also point out that by working with Iran on this nuclear deal, we were better able to address other issues.

My hope is Donald Trump makes things better. And if he does, we'll all benefit from it.

Americans coming home, an Iran that has rolled back its nuclear program and accepted unprecedented monitoring of the program -these things are a reminder of what we can achieve when we lead with strength and with wisdom, with courage and resolve and patience. America can do and has done big things when we work together.

Progress does not compel us to settle centuries-long debates about the role of government for all time, but it does require us to act in our time.

If you hear what people had to say about Abraham Lincoln or what they had to say about FDR, or what they had to say about Ronald Reagan when he first came in and was trying to change our approach to government, that elicited huge responses.

[This upset] means that means Donald Trump now has to transition to governance.

We are greater than the sum of our individual ambitions
