well. the koreans clearly dont think so. thats just the reality. actions speak louder than words. the pattern is, you get a new thing, they will soon get a better one. check the pattern of the past 20 years then we can talk.
Doesn't everyone do that? For example:
scenario 1:
-USA develops F22 program
-Russia and China develop their own 4th generation fighter
scenario 2:
-British Royal Navy builds a battleship
-German Navy builds a battleship, too
-French Navy builds a battleship, too
scenario 3:
-Japan develops Shinkansen
-Germany develops their own Shinkansen
-China develops its own Shinkansen "HSR"
scenario 4:
-Tadashi gets a girlfriend
-Tadashi's best friend, Masaharu, gets jealous and also gets a girlfriend to compete with Tadashi
-Tadashi and Masaharu go on a double date with their respective girlfriends
-Everyone is happy
scenario 5:
-Ling Ling gets a lollypop
-Yu Fang , Ling Ling's best friend, also wants the same delicious-looking lollypop
-Yu Fang goes home and asks her mommy to buy a lollypop from Uncle Wong's Store
-The next day Yu Fang shows off her new lollypop; Ling Ling smiles.
dont forget the dokdo/shima issue.
That's a tit for tat issue, and quite frankly everyone has the same around the world. I don't think this is a unique case for either Japan-South Korea, South Korea-China, or Japan-China.
That's just my view.
