It goes without saying that perspectives are important. Its not realistic to paint everything as black and white, right and wrong. Even with regards to North Korea and the Korean unification issue, some might see North Korea as the main antagonist, frequently citing its human rights abuses and its inhumane treatment of its citizens.
Ultimately, how one perceives a certain issue depends on which vantage point one is looking from. From North Korea’s perspective, U.S. is seen as the main antagonist/’enemy’ that is impeding the whole unification process, whereas its vice versa for the U.S.
And while the U.S. villianizes North Korea, China on the other hand chooses to see North Korea as its ally (though it is questionable if their current alliance is as strong as it was in the past).
The Korean unification should not be fixated on who is ‘right’ or who is ‘wrong’ for Korea’s separation, but instead focus on the need to have Korean unification – restoring the status quo of the Korean peninsula.
