I know how to make decisions and stand up to the criticism every day.

We are the safest large city in America, but any crime rate is too high.

Nobody wants a job where they don't have authority to go along with the responsibility. Quite the contrary. The more authority you give people, the better people you can attract, and the harder they're going to work, and the more loyal they are going to be.

I'm worried about the world because there's chaos in the Middle East, and I think the Iranian deal [to lift sanctions] is going to continue the Shia-Sunni battles, the Persian-Arab battles.

Millions of Americans have contributed to building a stronger Israel; I've been proud to be one of them. Last year, I went to Jerusalem to help dedicate in my father's name a new MDA medical facility which treats people of all faiths and all nationalities absolutely equally.

I cannot for the life of me understand why the American market keeps going up. Our economy has some real challenges. The infrastructure's falling apart. We're destroying jobs with technology. We are keeping the best and the brightest from around the world from coming to America to create new jobs and create new businesses. All of those things would give you pause to worry about the future.

New York has been, and will continue to be, a magnet for people from all over the world. This is where the arts, business, research and technology converge to create the world's foremost urban economy.
