Ultimately, only diplomacy can bring about a durable solution to the challenge posed by Iran's nuclear program. As President and Commander in Chief, I will do what is necessary to prevent Iran from obtaining a nuclear weapon. However, I have a profound responsibility to try to resolve our differences peacefully, rather than rush towards conflict.

As I've said many times, the nuclear deal was never intended to resolve all of our differences with Iran. But still, engaging directly with the Iranian government on a sustained basis for the first time in decades has created a unique opportunity, a window, to try to resolve important issues.

The politics around trade has always been tough, particularly in the Democratic party, because people have memories of outsourcing and job loss.

To those of you mourn the loss of a loved one today, my heart goes out to you. We remember that the blessings that we enjoy as Americans came at a dear cost. Our nation owes a debt to its fallen heroes that we cannot ever fully repay. But we can honor their sacrifice, and we must. We must honor it in our own lives by holding their memories close to our hearts, and heeding the example they set.

There's no straight line to progress.
