At first, the U.S. calculated that it could occupy the young DPRK easily by dint of its numerical and technical superiority.

The U.S. mobilized for the Korean War one third of its ground force, one fifth of its air force, most of its Pacific Fleet and over two million troops, including those from its 15 satellite countries, the south Korean army and the Japanese militarists. During the war the U.S. spent 165 billion US dollars as its military expenditure and used more than 73 million tons of war supplies, the amount of which was 11 times as great as the one it had used in the Pacific War.

At that time the number of troops and military hardware of the two-year-old DPRK was incomparably smaller than of the U.S.

However, the outcome of the war was contrary to expectations. The U.S. suffered tremendous human and material loss in the three-year-long Korean War.

During the war, 1, 567, 128 enemy troops were killed and captured. Out of them, 405, 498 were the U.S. troops.

In the three-year-long war, the U.S. lost 12, 224 airplanes, 3, 255 tanks and armored cars, 13, 350 motor vehicles, 564 warships and other vessels, 7, 695 artillery pieces of various kinds, over 925, 150 small arms, etc.

Such loss was 2.3 times as big as the one it had suffered in the four-year Pacific War.

The US News and World Report said that the loss suffered by the U.S. armed forces in the Korean War was over two times as great as the total loss they had suffered in the past five big wars such as the War of Independence, the war in 1812, the Mexican-American War, the Spanish-American War and the Philippine-American War.

Those in the American ruling quarters traded insults, shifting the responsibility for the great loss and humiliating defeat.

MacArthur, who had been called a "famous veteran commander", was dismissed after being held accountable for the shameful defeat on the war front. Ridgway, who took the post of commander of the U.S. forces in the Far East and commander of the "UN Forces" instead of him, was also dismissed for the defeat. Clark, who succeeded them and employed all means and methods to halt the decline, also disgraced himself at last by signing the armistice agreement, a document of surrender.

Loud lamentations about the defeat in the Korean War were heard in the U.S. after the conclusion of the armistice agreement.

MacArthur, then U.S. Secretary of Defense Marshall and then Chairman of the U.S. Joint Chiefs of Staff Bradley all lamented the disgraceful defeat unprecedented in the American history, saying that the U.S. was not strong enough and the Korean War was fought at the wrong time, in the wrong place and with the wrong enemy."

The U.S. had allegedly suffered no defeat in over 110 wars for 180 odd years since its foundation. But such "myth of mightiness" was utterly broken in the Korean War.

The Korean War in the 1950s, fought between the U.S. which boasted of the world's strongest and the young DPRK, can be called a "showdown between A-bomb and rifle".

The secret of the DPRK's victory in this confrontation lies in the Juche-oriented military idea, superb strategy and tactics and outstanding commanding art of the iron-willed brilliant commander, President Kim Il Sung, and in the indomitable fighting spirit of the Korean People's Army and all the people of the DPRK who bravely fought with the death-defying will against the aggressors, single-mindedly united around him.

Today, the DPRK has secured the military and technical edge and invincible war deterrent capable of annihilating any forces attempting a military confrontation with it at a blow under the wise leadership of the respected Comrade Kim Jong Un, supreme commander of the DPRK armed forces and ever-victorious iron-willed brilliant commander.

If the U.S. dares provoke the DPRK through reckless acts, oblivious of its defeat in the Korean War in the 1950s, it will inevitably face the worst-ever catastrophe.
