Not many people visit North korea these days but if you are one of the lucky few, more likely than not you will be led through an official guided tour of USS Pueblo – an American Intelligence vessel captured in 1968 – which remains the only American vessel currently in captivity.

The seizure of USS Pueblo is now one of the forgotten episodes of the Cold War. The U.S. claimed it was in the international waters, while the D.P.R.K. insisted that it was in the North Korean waters. Diplomatic and military stand-off that followed was punctuated by a series of photos, films, and letters depicting the crew of the Pueblo enjoying their comfortable captivity.

In reality, however, the crew was being subjected to psychical and psychological abuse. From behind the bars in one of the most isolated places on the planet, the crew nonetheless delivered a master class in political subversion. To undermine the credibility of the letters written home to suggest that they had willingly defected, the crew wrote about the events that never happened. In their press conferences, they used archaic words the Koreans didn’t perfectly understand. Since none of the Koreans knew English well enough to write the confession, the vessel’s commander wrote it himself. They checked the meaning of his words with a dictionary, but failed to catch the pun: “We paean the DPRK. We paean the Korean people. We paean their great leader Kim Il Sung”. (“Paean” is homophonic with “pee on”.)

And almost by accident, they came across the idea behind their greatest coup: in two propaganda movies, the crew noticed people giving the finger were not censored. The crew deduced that the North Koreans didn’t know what the finger meant. In the subsequent propaganda photos of the crew, their middle fingers were firmly extended to the cameraman. When the North Koreans questioned, the crew described it as the “Hawaiian good luck sign.” The ruse went on unnoticed until October 1968, when Time magazine explained the mysterious gesture appearing in many photos as one of “obscene derisiveness and contempt.”

This revelation infuriated the North Korean captors, bringing about a period of severe beatings and torture, and the propaganda letters, photos and videos stopped after this. Yet, it would take two more months for the U.S. to offer a perfunctory apology (retracted afterwards) to ensure the release of 82 crewmen. Diplomatic and morale victory hid the bitter reality that the loss of USS Pueblo was a significant blow to the intelligence services. It is now believed that the Soviets urged the North Koreans to seize the ship so that they can reverse engineer US equipment and codebooks.

Time Magazine never responded to the repercussions that followed its very public explanation, which in its entirely is reproduced below. For more photos, check the link here.
