The cession of territory would create everlasting bitterness, so it would be a fundamentally bad method. However, taking over Joseon's Matsushima (松島) would be a good thing.
The Korean writer claims that the "Matsushima" (松島) in the article was referring to "Dokdo" (Liancourt Rocks), but, of course, if such a thing was written, it would be much more likely that Matsushima was referring to Ulleungdo since, by 1882, Japanese were referring to Ulleungdo as Matsushima.
Does anyone have any links to the newspaper or know anything about the article mentioned?
The following is supposed to be a photo of the relevant page of the newspaper, which is apparently on display at the National Museum of Korea.
