Chuck Hagel: “As long as there is the threat of nuclear weapons... we have to maintain a safe, secure, and effective nuclear arsenal…”

This is so unpredictable. And we've never seen anything quite like this in our lifetime, so there is no playbook here.

This is really authoritarian.

No one person should ever govern a party. That’s not the point of political parties. Political parties must be diverse, have different opinions.

It just feeds into all that instability, and unrest, and unpredictability, which makes a damn dangerous world.
