Referring to the disclosure of secret information about the facts that the U.S. took into consideration long ago the emergence of the south Korean military as a ruling group after the collapse of the Syngman Rhee regime and remained indifferent to the occurrence of a military coup in the closing years of the Park Chung-Hee regime, the editorial went on:

A professor at Yonsei University of south Korea discovered at the U.S. National Archives a memorandum, which was reported to the director of the then CIA on April 21, 1960. It said that the conclusion of the U.S. ... was to remove Syngman Rhee from power and that the U.S. was almost certain to seek cooperation from the army of south Korea.

It also said that brass hats of south Korea had kept close touch with U.S. military and political representatives and the group was highly motivated.

A report sent by the then U.S. ambassador to south Korea to the State Department on April 20, 1960 said that when the south Korean regime asked for the mobilization of the 15th division of the south Korean army for the suppression of the demonstration and enforce a martial law on April 19, Lieut. General Cummings, acting Commander of the UN Forces, accepted the request and the U.S. ambassador okayed his decision.

The professor said that the U.S. approval of the military involvement on the basis of active consideration of a military coup at the time of the April revolution proved that its approval of the May 16 coup was a late realization of its scenario at the minimum cost.

According to other secret data, Donald Gregg, former chief of the south Korean branch of CIA, in a lecture at Texas State University in 1976 warned that if Park Chung-Hee remained in power for another six years as he desired, he would not be able to end the tenure of his office alive. Later CIA provided Park with information about a coup attempt, but it said it was uncertain whether it would continue to do so in the future, too.

The professor said that the remarks made by Donald Gregg could not but be shocking ones in view of the fact that there was a story about CIA's linkage with Park Chung-Hee's assassination on October 26.
