I think what Secretary Ash Carter is seeing, and I'm glad he is, is that we got to get NATO back working for the common defense. We've got to do more to support our partners in NATO, and we have to send a very clear message to Putin that this kind of belligerence, that this kind of testing of boundaries will have to be responded to. The best way to do that is to put more armor in, put more money from the Europeans in so they're actually contributing more to their own defense.

I want to invest in hard-working families.

We're working with our friends in the Middle East, many of which, as you know, are Muslim majority nations.

It plays right into the hands of ISIS. And that's why Americans need to know that Donald Trump's words are being used in recruitment videos that ISIS is putting out. I think that is a very serious problem.

Most of the gains in the last years since the Great Recession have gone to the very top. So we are going to have the wealthy pay their fair share. We're going to have corporations make a contribution greater than they are now to America.

Being human, we are imperfect. That's why we need each other. To catch each other when we falter. To encourage each other when we lose heart. Some may lead; others may follow; but none of us can go it alone.

It's also important that we look at the entire global situation. There's no doubt that we have other problems with Iran. But personally, I'd rather deal with the other problems having put that lid on their nuclear program than still to be facing that.
