Today, the United States is No. 1 in corporate profits, No. 1 in CEO salaries, No. 1 in childhood poverty and No. 1 in income and wealth inequality in the industrialized world.

Clearly we must do everything we can to protect our country from the serious potential of another terrorist attack, but we can and must do so in a way that also protects the constitutional rights of the American people and maintains our free society. We can do that without living in an Orwellian world where the government and private corporations know every telephone call that we make, every website we visit, everyplace we go.

At the end of the day, if millions of people come together and say, we are not going to be a xenophobic society, we are not going to be throwing millions of Latinos out of this country, we are not going to be a racist society, we're not going to be a sexist society, we will prevail.

I think the immediate thing is we stand up to protect those people who are in trouble.

Our goal there, in my view, is to work and lean strongly on China to put as much pressure. China is one of the few major countries in the world that has significant support for North Korea, and I think we got to do everything we can to put pressure on China. I worry very much about an isolated, paranoid country with atomic bombs.

I think we should look to countries like Denmark, like Sweden and Norway, and learn from what they have accomplished for their working people.

Countering violent extremism and destroying ISIS must be done primarily by Muslim nations with the strong support of their global partners.
