Kim Jong-un is no longer keen or clamoring for a Korean reunification, citing that the gulf between the two Koreas have become too great and distinct.
Is there any sliver of chance that if Taiwan doesn't get fully reintegrated back with the mainland under Pres. Xi's tenure that there's maybe a small potential or window of future Chinese leaders and people who may simply decide that gaining Taiwan back through military means may not be the best course for the country to make/take given the enormous costs of blood and treasure for China to make. Of course such ridiculous scenario can only be made possible if any and all support from all western and western supporting countries will permanently cease any military exchanges, military installations, military training with the Republic of China (Taiwan).
But, who are we fooling, America is hell bent on ensuring that regardless of China's deference, patience, and even to the point of benevolence towards America and the west; they want China to remain toothless, weak, and incompetent so that they can retain the hold, control and dictate the terms to the whole world just as they have done in the preceding decades.
Kim Jong-un further expounded on his thoughts with respect to the struggle of Korean reunification:
Reading his statements on this very pertinent issue re: national reunification and sovereignty, we could simply change the subject of Korea to Taiwan and the argument he put forth equally applies to the case of Taiwan.
