evidence: Tokyo’s new National Museum of Territory and Sovereignty opened this year, a permanent collection of historical documents highlighting Japan’s official territorial claim over the Diaoyu/Senkaku and the Dokdo/Takeshima islands. [...] The Liancourt Rocks, known as Dokdo in Korean and Takeshima in Japanese, are a group of two small main islets and 35 smaller rocks, with a total surface area of 46.3 acres, located 135 miles from Korea and 131 miles from Japan. While South Korea controls the territory, its sovereignty is contested by Japan. Interestingly, the unified Korean map does not show an indisputably Korean island, Ulleung-do, bigger than Dokdo/Takeshima and closer to Korea. [...] And conflicts over small territories may help maintain a certain geopolitical order. The Diaoyu/Senkaku and the Dokdo/Takeshima disputes have deep historical roots that go back to the 1951 San Francisco Peace Treaty and the 1971 Okinawa Reversion Agreement.
