I've been very sensitive for a long time to the repeated pattern, during economic hard times or after a war, of the United States' essentially unilaterally disarming.

There is no international problem that can be addressed or solved without the engagement and leadership of the United States and everybody in the world knows that, its just fact of life. So sometimes I think we could conduct ourselves with a little more humility.

I didn't think this whole business with Director James Comey was handled well. So there are sort of day-to-day aspects of the operation that I think are really troublesome. And I know that there are a lot of people in the country who have lots of issues with decisions that Donald Trump has making on the domestic side.

We should never lose sight of the ethos that has made the Marine Corps - where 'every Marine is a rifleman' - one of America's cherished institutions and one of the world's most feared and respected fighting forces

It has become clear that America's civilian institutions of diplomacy and development have been chronically undermanned and underfunded for far too long - relative to what we spend on the military, and more important, relative to the responsibilities and challenges our nation has around the world.

What I know concerns me. What I don't know concerns me even more. What people aren't telling me worries me the most.

Things have gotten so nasty in Washington.
