Those few days after Kent State were among the darkest of my presidency.

We cannot learn from one another until we stop shouting at one another - until we speak quietly enough so that our words can be heard as well as our voices.

History is a pathetic junkyard of broken treaties.

The ultimate test of a nation's character is not how it responds to adversity in war but how it meets the challenge of peace.

The memory of that scene for me is like a frame of film forever frozen at that moment: the red carpet, the green lawn, the white house, the leaden sky. The new president and his first lady.

I'm not a lovable man.
