Wikipedia actually doesn t strive to have cross article consistency at least not the way you mean In any event choice of name has only a little bit to do with who controls the islands and is instead based almost entirely on is commonly used in English Here Dokdo and Takeshima are used about equally in English so a compromise name was chosen However there s a lively debate going on at Talk Senkaku Islands if you have any factual policy based advice about what that article should be called you re welcome to give it over there
