First, you have said that "Takeshima is indisputably an inherent part of the territory of Japan, in light of historical facts and
based on international law."
However, after the Second World War end, Japan-where was
the war criminal country- had a unconditional surrender.
And Japan took out every territory where they had possessed
during the Second World War.
Second, you've said "The Republic of Korea has never
demonstrated any clear basis for its claims that it had taken
effective control over Takeshima prior to Japan's effective
control over Takeshima and reaffirmation of its territorial
sovereignty in 1905."
