We face now an era where we're going to be fighting the terrorist threat. I mean, that's simply a reality we are going to have to address that one.

Nothing keeps me awake at night. I keep other people awake at night.

North Korea is a direct threat to the United States. They have been very clear in their rhetoric we don't have to wait until they have an intercont- intercontinental ballistic missile with a nuclear weapon on it to say that now it's manifested completely.

I can't imagine that I would be asked that by the president-elect [Donald Trump], or then-president [Barack Obama]. But it's - I'm very clear. I voted for the change that put the Army Field Manual in place as a member of Congress. I understand that law very, very quickly and am also deeply aware that any changes to that will come through Congress and the president.

The first time you blow someone away is not an insignificant event.

We are going to have to continue to keep the pressure on the enemy. There is no room for complacency on this.

It is mostly a matter of wills. Whose will is going to break first? Ours or the enemy's?
