>bring back traditional Chinese characters

The Japanese people, through their democratically-elected representatives, chose to simplify many of their Kanji characters[0].

Should Japan also be forced to bring back traditional Japanese Kanji characters as well? What about Singapore[1]? I'm a little lost on which countries need to bring back their traditional characters and which needn't.
