What the fuck are you talking about? Japan before Hideyoshi was very different, it was backwards, undeveloped and not at all an advanced civilization. In fact Korea and China would call Japanese 'midgets' as racial slurs and 'barbarians' because they didn't even wear proper clothing and smelled like dog shit.

Baekje was a Korean kingdom in decline and was destroyed by the Silla kingdom from South-East Korea. Baekje people pretty much fled the Korean peninsula and emigrated en masse to Japan where they pretty much transformed it from the dirty shithole it was to a well organized state.

The first Korean president had an American wife, not Austrian, you make it sound like he married an Austrian native.

Korean princes were married to Mongolian princesses, so were the rest of the countries they pillaged and controlled (about 1/3rd of the world's population) not just Korea.

Actually most Koreans don't give a shit, it's only those politically weak to make their own call that they buy into the anti-Japanese rhetoric. Most Koreans think Japan is a pretty well off country and like that it's politically stable unlike Korea where it has to fight off constant threat of North Korean subversion and sympathizers.

Why would Koreans hold contempt for the current Japanese emperor, he didn't start the rape of Asia, his daddy did, and he got a good spanking from a white man so that's the end of that.
