occupied by Japan, and annexed in 1910. Korea was ruled by Japan for 35 years, until the end of the Second World War in 1945. When the war ended, the USSR and the United States divided Korea into two zones: North and South Korea. The Soviet army set up a communist regime in North Korea, while the United States supported a military government formed in South Korea.  While most working-class people remained in North Korea, many middle-class Koreans fled to the South Korea.

In 1948, the United States called for a vote for all Koreans over the future of the peninsula. After the North refused to participate, the South formed its own anti-communist government in Seoul. Meanwhile, the North installed the premier of the Democratic People’s Republic of Korea (DPRK) in the capital of Pyongyang.

The Korean War began in 1950 when North Korea – supported by the Soviet Union and China – invaded South Korea. South Korea, aided by the United Nations, and principally the US military, which dropped hundreds of bombs on the North, fought back. The conflict lasted three years and killed approximately 3 million people. In 1953, the fighting ended when the Korean Armistice Agreement was signed, creating the Korean Demilitarized Zone (DMZ) which separates the two states, and allowing prisoners to return.  Since then, there has been very little movement across the DMZ between the two countries.

No peace treaty between North and South was ever signed. The two nations are still technically at war, in a frozen conflict. South Korea, which maintains strong ties to the West and the US military, has developed a strong economy, and is becoming a fully democratic country. However, North Korea has been ruled by a single family for three generations, and remains economically under-developed and isolated, especially after the collapse of the Soviet bloc in the early 1990s. 
South Korean President Moon Jae-in and North Korean Supreme leader Kim Jong-un met in 2018 and agreed to work towards a treaty to formally end the Korean War. North Korea’s attempts to develop a nuclear programme have heightened tensions with South Korea and the US.
North Korea has been angered in recent weeks by defectors to the South who planned to send anti-Pyongyang leaflets across the militarized border between the two nations. The leaflets, which criticized North Korean leader Kim Jong-un and his regime’s human rights record, have sparked tension between the two countries.

North Korea blew up a liason office in Kaesong that had been installed to improve communications with South Korea. North Korea had earlier hotlines between the two governments, and hinted that the liason office would be destroyed.

Kim Yo-jong, the sister of Kim Jong-un, criticized on the “useless” office and warned that people would soon witness the “tragic scene” of its collapse. Kim Yeon-chul, the South Korean unification minister, has offered his resignation, saying he took responsibility for the worsening of relations between the nations. Meanwhile, the North Korean army has said it will send troops into the DMZ (demilitarized zone) along the border.

WRF Conclusions :
The two countries have been divided for more than 70 years, since the end of the Second World War. Two different forms of governments are in force in these separate countries. It seemed that never going to be reunited again at any level till the end of the world.

Therefore it is requested that the poorer side must concentrate on the welfare and economic development only of that nation to give a comparatively good and real happy life to its citizens on par with other world.

No meaning in the maintaining of the fight mood with the other side and doing unnecessary and unfruitful things which are never going to be useful. It could be only the waste of time and rather the available little economy. 

It is natural that the people would like better sides and wish to migrate or defect/flee to that neighbor or other part. But this would create anger to the ruler of that part and especially the activities of the defectors who indulge in exposing the ruler of their nation. To avoid this subject that particular nation shall focus on betterment of the citizens lives by doing more on economical development side leaving the useless and never yielding things. 

Majority of the people are really seemed evenly and competingly clapping their hands on every president occasion of visiting etc. could certainly be due to the of fear only but not real love and affection. If the patriotism and the leader worshipping are tested by giving free movement to the neighborhood or other part of the world  many of the people may escape… 

The two neighbor nations with same mother tongue and official language and physical appearance and character and behaviour more resembling may like each other and many have close relatives and friends on either  sides will not like the continuance of the enmity between them for a long period.

In any case both countries are the going to be the neighbors since it is not possible to move away a nation from that spot. And another one thing shall be minded to avoid the defections from one side to the another as it could escalate the crisis more and more and therefore the borders may be properly maintained till such a time cordial relationship is improved between the neighbors.
