BEIJING –

On June 11, The Washington Post Beijing bureau chief Anna Fifield's new book, "The Great Successor" will be published by PublicAffairs. The Japan Times’ contributing writer Martin Laflamme discusses with Fifield the experience of writing her book, how she tracked down sources and her thoughts on Kim Jong Un’s North Korea.

Many defectors told you that even before they fled North Korea, they understood that much of the propaganda was bunkum. Some even used very explicit language to say that Kim Jong Un was "a piece of s—-," that he was "not capable" and that "they knew the truth." However, given the constant indoctrination and state of total surveillance that is prevalent in North Korea, such views are surprising. Is it possible that these thoughts were formed after the defectors fled and then projected backwards?

Many North Koreans know that their country is not the socialist paradise it's cracked up to be because the vast majority have seen movies and dramas from the outside world. I have not met a single escapee from North Korea during Kim Jong Un's reign who hasn't watched outside media. They've seen soppy South Korean rom-coms, they've seen Chinese action films, they've seen Bollywood hits. Some have even seen pornography. So they know that the outside world is much richer and freer than North Korea. But even armed with this information, most are unable to do anything about it. The system of punishment is so severe and all-encompassing in North Korea that people who criticize the regime, or even express a desire to live in South Korea, could find themselves in a hard labor camp for the rest of their lives, perhaps with their parents and their children and their spouse. Faced with that prospect, North Koreans try to leave rather than try to change the system. So I believe them when they said they knew the truth while they were there.
