I think China and SK need to grow up then..the world has changed.
If the year was 1982, and the world shifted, smashing the USSR and USA together as border neighbors...I would be horrified at the process.
now, many years later and a bit of intelligent diplomacy later...I would think it to be great...the two cultures could learn alot from each other, and
I think the time of nuclear exchanges and war to be a relic mindset of the past...
Same with Japan, or Germany...
nations grow up..and with that, border concerns also need to start disappearing...China doesn't make me nervous...I am not happy about many things
they do over there...but I see them as constantly developing and will self correct without need for our interference...they need to see a border
between korea (south korean expanded to encompass all of korea) as no longer some wacky threat, but a economic opportunity that it would be.
