> It is universally agreed between the two governments (and their citizens) that a unification should happen at some point, so it is obvious that we should be using a map that covers the whole peninsula. We (as South Koreans) also learn 'our country' as the whole peninsula.

When I was growing up, I learned that too. But is it still true? I don't see any unification news or mention of it from media anymore. I don't think that schools still say or can say that to students. It didn't take me a long time after I got out of the public education system to realize what propaganda schools and media were selling.
