What If South Korea Won The Korean War (Part 1)

Korean War are ended in 1953, with no obvious winner. The border before the war and after the war it don't experience extreme changes. Because that, I will write this in 2 part, one if South Korea win and the second is how if North Korea win the war. So, stay tune!

Syngman Rhee

1. Whole Korean Land Are Below Syngman Rhee Regime
Syngman Rhee is the president of South Korea, from 1948-1960. He is can be compared to Kim-Il-Sung, it North Korea's opponents. Still, even if his dictatorship are not as severe as North Korea dictatorship, he still have some "reputation", such as suppressing Jeju Uprising, killed 14.373 people, 86 percent of death is because government anti-communist force.
So, how if he can control whole Korean? The communist people at North Korea will be suppressed, the Communist people are become an object of massacre. Hundreds of thousands people can be killed by Syngman Rhee regime's troops. The other communist, are flee to China and Russia. The communist that don't become massacre object, or flee to China, are live in concentration camp, or hiding in mountains and forest waiting when the Communist back to power.

2. China Position Are Threatened.
With Korea in pro-America regime hands, the US can easily attack China via land, and attacked it from the air. Attack China from Korea is far more easy than attack from Japan. If US attack China from Japan, it troops must face very long journey across Sea of Japan, and the history says amphibious assault are have very expensive cost, thousands of people die and many vehicle are destroyed. Attacking via air is also difficult, the US combat plane can't reach inner China from Japan.
If US attack via Korea, it can save many live. US can using large number of troops, not like amphibious assault that can only using small number of troops. And if US attacking China using plane, it can reach inner part of China. One of other tactics is attack China from Korea and Japan at the same time, thus making China attacked from 2 side. Using this strategy, US can conquer China easily.

3. Korea Development Will be Faster
South Korea and North Korea, if compared, like Earth and Neptune. South Korea are one of most democratic nations, at the 21st ranking from 167 countries that being surveyed (Economist Intelligence Unit). Meanwhile the North Korea is the world most undemocratic countries, 167th ranking from 167th countries that being surveyed (Economist Intelligence Unit). South Korea are in 15th ranking for Human Development Index. Meanwhile, you can guessed it, North Korea will be in bottom place if it's included in HDI survey (North Korea doesn't included in this survey, because not enough data).
So, what if North Korea under South Korea government? It economy will be still under Southern part of Korea, but it's lot better than North Korea under Kim-Il-Sung.

4. Chinese Attack Threat!
Because China has losses it position at Korea Peninsula, it's not impossible if China want a revenge. China, helped with Soviet Union and North Korean army that takes refugee at China. China was notable for its large army, the Soviet Union have high technology, and North Korea Army have high nationalism. But, because Korea is protected by USA and it ally, the war between these nations are only reach border war state. It border maybe only change for 8-10 km, and these will be stalemate. These war maybe reach the end of China patient and China attacked Pyongyang, Seoul, and Busan with it nuclear weapon. After first strike, America, is will counterattack the China, by launching it Peacekeeper and Minuteman missile to China largest city, Beijing and Shanghai. This war will happens for few moment, and it stop if China and Korean land turned into radioactive land and hundreds of crater are spreads around this two countries.
