I’ve often been asked about this personality trait — my ability to maintain composure in the middle of crisis. Sometimes I’ll say that it’s just a ma… - Barack Obama

We’ll continue to help India deal with the impacts of climate change -- because you shouldn’t have to bear that burden alone. As we keep working for a strong global agreement on climate change, it's young people like you who have to speak up, so we can protect this planet for your generation. I'll be gone when the worst effects happen. It's your generation and your children that are going to be impacted.

The role of citizen in our democracy does not end with your vote. America's never been about what can be done for us. It's about what can be done by us together through the hard and frustrating, but necessary work of self-government. That's the principle we were founded on. This country has more wealth than any nation, but that's not what makes us rich. We have the most powerful military in history, but that's not what makes us strong. Our university, our culture are all the envy of the world, but that's not what keeps the world coming to our shores. What makes America exceptional are the bonds that hold together the most diverse nation on earth. The belief that our destiny is shared; that this country only works when we accept certain obligations to one another and to future generations. The freedom which so many Americans have fought for and died for comes with responsibilities as well as rights. And among those are love and charity and duty and patriotism. That's what makes America great.

But how can we in good conscience justify war before we’ve tested a diplomatic agreement that achieves our objectives; that has been agreed to by Iran; that is supported by the rest of the world; and that preserves our options if the deal falls short? How could we justify that to our troops? How could we justify that to the world or to future generations? In the end, that should be a lesson that we’ve learned from over a decade of war. On the front end, ask tough questions. Subject our own assumptions to evidence and analysis. Resist the conventional wisdom and the drumbeat of war. Worry less about being labeled weak; worry more about getting it right.
