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.

In a country with millions of people & cars going everywhere, the enemy is going to get a car bomb out there once in a while.

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.

Congressman [Mike] Pompeo said he believes the intelligence agencies' claims that Russia hacked the US election.

Find the enemy that wants to end this experiment (in American democracy) and kill every one of them until they're so sick of the killing that they leave us and our freedoms intact.

The destruction that we have wreaked in the various theaters in which we've been engaged is really quite astonishing. But again, lethality, destruction, killing doesn't seem to achieve our objectives. So, my own sense is that a lack of lethality does not define the core problem.

Our strategy right now is to accelerate the campaign against ISIS. It is a threat to all civilized nations.
