I worry most about proliferation of weapons of mass destruction in such a way that they could be acquired by non-governmental organizations, like terrorist groups, especially the radical groups. When a nation state has a nuclear weapon, it's a little bit easier to control the use of it, but for non-governmental groups it's much more difficult.

We are United States Marines, and for two and a quarter centuries we have defined the standards of courage, esprit, and military prowess.

It's OK to have fun in the Marine Corps. I like to say we are an imperfect people working in an institution that tries to be perfect. That is a noble thing, but you have to realize there is no perfect. We're human.

Ensure that no Marine who honorably wore the eagle, globe and anchor is lost to the Marine Corps family.
