According to a survey of 1,083 middle- and high-school students nationwide, 70.3 percent of the respondents said that reunification is needed.For at least some, the reason for this conclusion is based less on the essential indivisible unity of the Korean people and more on the implication of a unified Korea on regional geopolitics:
"Japan and China have recently made territorial claims over our land, which I believe resulted from our weak national standing," Kim said.
"Through reunification, the two Koreas can complement each other's weaknesses and become a more powerful nation so that other countries would not vex us over such sovereignty issues."
Also nice to know that South Korean students (at least 3/4 of them) remember at least a little of the history they are taught in school:
The survey also found that 73.2 percent of the respondents were aware of when the 1950-53 Korean War broke out.
