Upon Liberation , the Process for building a nation

Upon Liberation , the Process for building a nation ... 
On August 15, 1945, Japan surrendered unconditionally to the Allied forces, and that finally brought an end to the war. Japan's defeat meant the independence of Korea, since in 1943 the leaders of America, Britain , and China held a conference at Cairo to discuss of post-war Asia and promised the independence of Korea; In due course , Korea shall be free and independent.
Koreans welcomed the day of independence with delight and also tears. Korean flags, which had been hidden in people's houses, stormed the streets and shouting "Hurray for Korea's Independence!" trembled the earth and heaven.
It was the Korean and Chinese Nationalist movements that mostly fought the Japanese prior to 1941.

 

Then in 1941 the United states of America emerged as the new leading force of the Allied forces, and in 1945 the Soviet union finally joined the Allied forces as well. And after the war ended, America, China, Russia created a new world order. America attempted to place Korea under a trusteeship for a certain period of time, since they needed a pro American government in Korea.

The Soviet union also marched into the Korean peninsula to establish a pro Russian government...Koreans' wishes to establish their own government were mostly ignored.
The United states and the Soviet union respectively occupied the southern and northern areas of the 38th parallel.
