Decades on, thousands of troops still in South Korea

When President Obama continues his week-long Asia trip today in South Korea, he’ll get a look at the long aftermath of the Korean War. There are still approximately 28,000 United States soldiers stationed in South Korea. That’s about 12,00 fewer than six years ago. Joining us now to explain why there are still so many U.S. troops committed is Robert Kaplan, senior fellow at the Center for a New American Security, and a correspondent for The Atlantic.
