We have got to dispel this myth that bullying is just a normal rite of passage.

The president does not have power under the Constitution to unilaterally authorize a military attack in a situation that does not involve stopping an actual or imminent threat to the nation. As commander in chief, the president does have a duty to protect and defend the United States. In instances of self-defense, the president would be within his constitutional authority to act before advising Congress or seeking its consent.

If we aren't willing to pay a price for our values, then we should ask ourselves whether we truly believe in them at all.

To this day, the United States is profoundly grateful for our friendship and alliance with Greece.

One of the proudest things of my three years in office is helping to restore a sense of respect for America around the world.

If fake news that's being released by some foreign government is almost identical to reports that are being issued through partisan news venues, then it's not surprising that that foreign propaganda will have a greater effect, because it doesn't seem that far-fetched compared to some of the other stuff that folks are hearing from domestic propagandists.

What is true, and I think that we can't deny it, is that some of the same concerns about globalization, about technology, rapid social change that were reflected in Brexit, that's been reflected in some of the debates in Germany and France and other places, that those exist in the United States as well. My view is that over the long term, over the next 10, 15, 20 years, if we are able to address the legitimate economic concerns of those who feel left behind by globalization, then many of these tensions will be reduced. And we will see a world that is less divided.
