Israel has legitimate concerns about its security relative to Iran. I mean, you have a large country with a significant military that has proclaimed that Israel shouldn't exist, that has denied the Holocaust, that has financed Hezbollah, and as a consequence, there are missiles that are pointed towards Tel Aviv. There are very good reasons why Israelis are nervous about Iran's position in the world generally.

As for Israel, our friendship is rooted deeply in a shared history and shared values. Our commitment to Israel's security is unshakeable. And we will stand against attempts to single it out for criticism in international forums.

In Iraq and Syria, American leadership - including our military power - is stopping ISIL's advance, instead of getting dragged into another ground war in the Middle East, we are leading a broad coalition, including Arab nations, to degrade and ultimately destroy this terrorist group.

What I've said is we're going to encourage democracy in Pakistan, expand our nonmilitary aid to Pakistan so that they have more of a stake in working with us, but insisting that they go after these militants.

Maybe at the same time as I'm more confident today, I'm also more humble.

Our country was born out of a desire to be free. And every day since, it's been protected by our men and women in uniform - people who believed so deeply in America, they were willing to give their lives for it.

One of the things I think I can bring to the presidency is to make government and public service cool again.
