As a journalist, I've felt as if it's a privilege that people share their stories and want you to be the messenger.... Even in my current job, when I go abroad, I'm racing to get back to the president and the secretary to share what I've seen.

As even a democracy like the United States has shown, waging war can benefit a leader in several ways: it can rally citizens around the flag, it can distract them from bleak economic times, and it can enrich a country's elites.

My second epiphany came as an intern at the Carnegie Endowment for International Peace. The man I worked for was consumed with what was going on in Bosnia.

I think that the only time we will really know what then-President Trump is going to do about the set of challenges that confront him is after he has sat down with his advisers as the commander in chief, when he's looking at the threats and the intelligence from the standpoint of being the number one decider, when he's hearing from his secretary of defense, his chairman, who was the same chairman President Obama had, Chairman Joe Dunford, who is an outstanding public servant, who has led our anti-ISIL effort, on which we're making great progress.
