All national leaders are fussy about whom they let starve and brutalize their own people, Teribus. ;-) It's called "turf mentality" or something like that ("These people are MINE, not yours, to brutalize. Keepa you hands off!"). Nationals leaders always claim to speak for their people, but their behaviour more generally seems to indicate another assumption altogether: that they own their people, and their people's main function is to serve the system and obey orders until they die.

Those who won't obey orders find out fast what the real score is. This is true in "democracies" as well as in dictatorships, only thing is, it's a lot worse in dictatorships.

There seem to be a good many Korean voices in favour of re-unification. That would be a very good thing. Japan would not like it, because they fear a stronger Korean nation next door to them. The USA, China, and Russia would not like it, because then they could not play quite as much dirty "divide and conquer" politics in the region. The present rulers of North and South Korea probably wouldn't like it, because they might stand to lose some of their power.

It looks, in fact, as if the only people who would like it are ordinary Korean citizens. That's typical. Divide and conquer tactics are always perpetrated upon the many at the bottom by the few at the top.
