KOREAN ARMY.
TONIGHT U.S. OFFICIALS TELL CNN 
THEY WON'T COMMENT ON THEIR 
ANALYSIS OF THIS STUNNING NORTH 
KOREAN PROPAGANDA TAPE.
THE VIDEO FEATURES TWO BROTHERS 
OF AMERICAN HERITAGE IN 
PYONGYANG, SPEAKING IN WHAT ONE 
EXPERT CALLS A NORTH KOREAN 
ACCENT AS THEY PLEDGE THEIR 
LOYALTY TO KIM JONG-UN AND SLAM 
THE UNITED STATES.
>> Translator: THE AMERICAN 
IMPERIALISM, THE UNITED STATES 
WANTS TO CONQUER THE WORLD, 
PURSUING ANTI-NORTH KOREAN 
POLICY, TRYING TO TAKE OVER 
ASIA.
>> Reporter: U.S. BASED SOURCES 
SAY THE STORY OF HOW THE MEN WHO
ARE HALF AMERICAN CAME TO 
SUPPORT THE NORTH KOREAN 
DICTATOR BEGAN MORE THAN 50 
YEARS AGO, BEFORE THEY WERE 
BORN.
THEY'RE THE SONS OF JAMES JOSEPH
DRESS KNOCK, FORMER AMERICAN 
SOLDIER THAT DEFECTED TO NORTH 
KOREA IN 1962.
>> Translator: THE UNITED STATES
MUST ABANDON ITS ANTI-NORTH 
KOREAN POLICY.
ITS DONE A LOT OF BAD THINGS. 
>> Reporter: THEY WERE BORN IN 
NORTH KOREA AND BY ALL ACCOUNTS 
NEVER LIVED OUTSIDE THE COUNTRY.
JAMES SAYS HE IS A CAPTAIN IN 
THE NORTH KOREAN ARMY.

A HUMAN RIGHTS ADVOCATE KNOWS

BECAUSE THEY'RE SUCH A GREAT 
PROPAGANDA ASSET.
>> Reporter: THE BROTHERS AND 
THEIR FATHER ACTED IN NORTH 
KOREAN PROPAGANDA MOVIES, 
PLAYING THE EVIL AMERICAN.
AS FOR THIS INTERVIEW IT IS NOT 
CLEAR IF THE BROTHERS WERE 
FORCED TO SAY THOSE THINGS OR IF
THEY REALLY BELIEVE THEM. 
>> REMEMBER THESE TWO BROTHERS 
WERE BORN IN NORTH KOREA.
IT'S THE ONLY WORLD THEY KNOW.
WHATEVER THEY WERE TOLD ABOUT 
THE OUTSIDE WORLD I AM CERTAIN 
WAS VERY LIMITED AND PURPOSELY 
CHOSEN AND SELECTED.
>> Reporter: HUMAN RIGHTS 
ADVOCATE SAYS HE DOESN'T THINK 
JAMES AND TED WOULD BE ALLOWED 
TO LEAVE NORTH KOREA, EVEN IF 
THEY WANTED TO.
WOULD THEIR FATHER BE PUNISHED 
BY THE U.S. MILITARY IF HE LEFT?
