竹島

国際法上は、92km離れている島を「付属島」と解釈することはできないんですがね。
SOVEREIGNTY OVER PULAU LIGITAN AND PULAU SIPADAN
The Court further recalls that it stated above that the words “the islets belonging thereto” can only be interpreted as referring to the small islands lying in the immediate vicinity of the three islands which are mentioned by name, and not to islands which are located at a distance of more than 40 nautical miles. The Court therefore cannot accept Indonesia’s contention that it inherited title to the disputed islands from the Netherlands through these contracts, which stated that the Sultanate of Bulungan as described in the contracts formed part of the Netherlands Indies.

まぁ領海内（1905年やSF条約時は2〜3海里）の島については、他国に権原がない場合については、沿岸国領土との「強い推定」が働きますがね。
There is a strong presumption that islands within the twelve-mile coastal belt will belong to the coastal state, unless there is a fully-established case to the contrary.

国際法が通じない非文明国民に何を言っても無駄でしょうけど。
