LOL! No, they wouldn't. I can't believe he would say that. There is still hostility to Japan among some in Korea.
I think the animosity between Japanese and Koreans is over-stated by the media.
Koreans are a tetchy bunch.
The Japanese were there to loot raw materials. They did nothing for Korean industry.
I knew someone who was in Korea immediately after WWII.
His comment about Korean auto imports in the 80s was “When I was there they couldn’t even make a watch.”
And many Japanese are angered that Koreans still own some of the best bars in Tokyo, forced on them during the Post-WWII occupation.
Remember, to a Japanese, any other nationality is totally inferior to Japanese. As a Japanese client told me, after he was a bit surprised that we do not have the same attitude, “To many Japanese, a Japanese mass murderer is a better person than a Korean Nobel Prize-winning physician, or any Chinese, Vietnamese, Indonesian, American too.”
We in America can hardly imagine what it is like to be occupied by a tyrannical empire. We measure our social cues by hours. Why hold a grudge for forty years? Our media people need to read a book once in a while.
