"Isn't a country, widely recognised however"? Huh? If its widely recognised, its a country! More countries recognise Palestine (70% of the world's countries, in fact) than Kosovo or Taiwan, which no-one disputes are countries; and while being largely occupied by Israel, especially in the West Bank, that does not stop Georgia and Cyprus, also partly occupied, being accepted as countries.
Georgia and Cyprus have a historical claim to their land, having been their for centuries. Kosovo and Taiwan are opposed only by a few countries who have natural vendetta against them (notably China for Taiwan and Serbia for Kosovo, who owned the land previously). Palestine, however, has neither of these things, and is just a pseudo-country declared during the turmoil of various nearby countries attacking Israel. If Palestine had taken advantage of these circumstances to actually take control of the land, then they would be a country, but Israel has been in the Palestinian area dating back over 3000 years, whereas Palestine's claim isn't even thirty years old.
The Taiwanese and the Chinese do not have a 'natural vendetta' against each other. In fact, they both agree that there's only one China. It's just that they both think they are it. Power-hungrily speaking. Most civilians, in fact, do not care. They would be perfectly happy to have these separate nations and go on with their individual lives. Only the politicians and the nationalists are bickering over the issue. This educated opinion is based on Asian studies, knowing a lot of people on 'both sides' and living over there. It's true, though that be there a political cockfight, the politicians (on all sides) use the tool that psychologists call "hostile imagination" and insert it in their citizens for political points and the suffering of your regular Mr and Mrs Cheng. The case of Israel (Palestine/Jordan) is also interesting and sad. War over a book and its interpreters' hunger for power, simplifying. Otherwise, just people, same people. Used to live and prosper in .. Peace
And to further the point, more countries recognise Taiwan. Oh, and lots of people dispute whether Kosovo is a country. I mean, they're wrong, but still.
Maybe accept France for French Guiana? I got the answer nonetheless, but when people debate about whether to include French Guiana they debate about whether to include France.
That is true actually. I'm surprised by how little controversy the Sinai Peninsula generates on this site (although the days of people arguing about such trivial things in the Jetpunk comments are sadly over, for the most part).
