It is absolutely important that we have a unified alliance and that we explain to the Russians that you cannot be a 21st-century superpower, or power, and act like a 20th-century dictatorship.

I think it is possible for the world to see a Palestinian state - I'm not going to put a time frame on it - that is contiguous, that allows freedom of movement for its people, that allows for trade with other countries, that allows the creation of businesses and commerce so that people have a better life.

Iran has to live up to its international obligations. . . . The president has said that our patience is not unlimited.

I think that there is a particular mindset that was on display in the run-up to the Iraq war that continues to this day. Some of the folks who were involved in that decision either don't remember what they said or are entirely unapologetic about the results, but that views the Middle East as a place where force and intimidation will deliver on the security interests that we have, and that it is not possible for us to at least test the possibility of diplomacy.

I have nothing to hide. I enjoy being myself. I'm not going to change who I am just because it's Halloween.

My goal is to maintain the international norm on banning chemical weapons. I want that enforcement to be real. I want it to be serious. I want people to understand that gassing innocent people, delivering chemical weapons against children is not something we do. It's prohibited in active wars between countries. We certainly don't do it against kids. And we've got to stand up for that principle.
