Truman ignited a war of aggression against the two year-old DPRK on June 25, 1950, but drained the cup of shameless defeats in the whole course of the war.

After succeeding Truman as the U.S. president, Eisenhower made every desperate effort to roll back the tide of war, but the Korean war ended in the great victory of the heroic Korean people led by President Kim Il Sung, iron-willed commander, on July 27, 1953.

When the U.S. spy ship "Pueblo" was captured by the navy of the Korean People's Army on January 23, 1968, the U.S. shrunk back from the tough stand of the DPRK army and people, who declared they would react to the U.S. "retaliation" with stronger counteraction and to the total war with all-out war, and had to made a written apology to the DPRK.

At that time, U.S. President Johnson deplored that it was the one and only written apology the U.S. made in its history. And Washington Post reported the U.S. got a bloody nose by a small country.

Nixon, oblivious of the lesson drawn from the "Pueblo" incident, fomented the EC-121 incident in April 1969 just after winning the presidency and Ford provoked the Panmunjom incident on August 18, 1976 in a bid to concoct an excuse for the start of a new war against the DPRK, all of which resulted in U.S. failure.
