America

North Korea’s biggest enemy is the United States.

Pyongyang’s upper tier are enthusiastic fans of Hollywood cinema, but the commoners are infused with completely different stories. Americans are depicted as worse enemies than Japanese. The Japanese were beaten by the brilliant General Kim Il Sung and partisan of the hundred battles and were driven out of Korea.
But Americans are still there, hurting and exploiting the poor South.
The south is a land of despair and hunger, and its people dream of being free from yoke. All US missionaries are evil spies, and their greatest pleasure is killing Korean children, sometimes in a sadistic manner. U.S. diplomats are bloodthirsty paranoids who spend more than 10 hours a day trying to get rid of the Koreans. (Andrey Lankov, North of the DMZ: Essays on Daily Life in North Korea)

In North Korea, school children receive thorough anti-American education.

I never said “American”. That’s too polite. I had to say “American guy” or “Yankee devil” or “Yankee with big nose”. Otherwise, he would be accused of being too sweet for his enemies. (Park Yong-mi, “The Choice to Live”)
Even if I heard the name of the United States, I got an anti-American sentiment as the goose bumps quickly rose. Anti-American thought was educated through movies and other means. In the north, it has been pointed out to the United States that it has been taught that it is “an enemy of the insecure, who cannot live with my people and one heaven together.” (Kim hyon-hui “as a woman”)
In caricatures, Americans were routinely depicted in jackallings, peeling their teeth and groaning.
Propaganda posters are usually depicted as sticks, thin nose, and blond hair.
Americans were taught to smell bad. They have turned the southern half of the Korean Peninsula into hell on earth, where they hold their puppet government. (Lee Hyun-so, “A Girl with Seven Names”)
