For the United States to recommit itself to the obligation that we undertook in the Nuclear Non-Proliferation Treaty that many other states undertook, which was to work towards disarmament and the eventual elimination of nuclear weapons, is something that manifestly serves our national security interests.

You can't sit on the sidelines and read your iPhone and be on social media and expect everything to be cool. You have to be part of this.

We have been very clear that Israel has an undeniable right to self-defense and that the rockets that it has faced coming out of Gaza incessantly, the tunnels that are legion and are being used to infiltrate into Israel are very legitimate security concerns, for which they have an obligation - against which they have an obligation to act.

I'm apologetic when I feel like I've made a mistake. And when I have done a disservice to myself or someone else. But I don't feel a need to apologize for doing or saying something that I think needs to be said, just because it may not sit comfortably with somebody else.

I would rather be alone and a loud voice for action than be silent.
