How does the sentence end?

(CNN) -- Living at the China-North Korea border, I had the unique opportunity to train under two North Korean tae kwon do masters. While I told people I was there to learn the rare North Korean martial art from some of their best instructors, I was secretly helping North Korean refugees on the 6,000-mile modern-day underground railroad from the Hermit Kingdom to South Korea, for food and a better life. In 2004, I traveled to North Korea to see the country, even though many people warned me not to take the risk. One of our detained Chinese workers later said that North Korea had a file on me, but did not know my name. I lived with the fear of being detained, abducted or assassinated by the North Korean government for many years. Whenever I hear of another American detained, it reminds me of that anxiety.

It wants to use the three
American as bait but not anger the United States so much that a high-ranking envoy will not come to the negotiating table.
