Kerry wants to put me out of business!

And part of that leadership is sending the right message to places like North Korea. Right now the president is spending hundreds of millions of dollars to research bunker-busting nuclear weapons. The United States is pursuing a new set of nuclear weapons. It doesn't make sense. You talk about mixed messages. We're telling other people, "You can't have nuclear weapons," but we're pursuing a new nuclear weapon that we might even contemplate using.

Not this president. I'm going to shut that program down, and we're going to make it clear to the world we're serious about containing nuclear proliferation.
