Bolded bits in your opinion, of course.
Japan isn't connected to the Asian mainland but I am sure they consider themselves Asians. Same would go, I'm sure, for Sri Lanka, Taiwan and Indonesia. None of these countries are on the Asian mainland, yet no-one, AFAIK, tries to pretend that they are not in Asia.
Closer to home, I'd be surprised if Ireland and Iceland, much further from the European mainland (and nearer to another continent, North America, than we are) try to deny that they are part of the geographical continent of Europe.
Sorry, but I just intensely dislike the geographically-illiterate, politically-motivated, British-exceptionalist claim that the UK is not part of the continent of Europe. Do significant numbers of citizens of
any other island nation in the world try to pretend that their country is not part of its continent?
And the rest of Europe does "look to the world". Are you trying to tell me that France and Germany, for instance, do no trade with the rest of the world? Can you not fly to a wide range of global destinations from Frankfurt, Schiphol and Charles de Gaulle?
But this is all probably something worth discussing on another thread (mods, feel free to move this post to a new thread....)
