I saw the question Is there a list of online public transportation planners?. I want to add information for Israel. Should I add it under the common wiki answer for Europe, or in a new answer?
It's technically an associate state of the European Union, so politically is loosely affiliated, but geographically, it'd be tricky to argue...generally the Bosporous river in Istanbul separates Europe from the rest of the world, and therefore arguably it's not in Europe by that definition...
I agree with @RoflcoptrException that Israel is NOT in Europe. You gave some examples with Malta und Cyprus, but don't forget that they are islands, and Israel is not. They were both British colonies and Greek Cypriots form up to 80% of the Cypriot population.
We can discuss if Cyprus and Malta are part of Europe, but Israel is definitely not.
Beyond all abstract historical/political/cultural considerations and the general “gut feeling” some Europeans seem to have, I feel Israel (and Turkey!) should be mentioned/linked in the page about Europe. Obviously none of these categories are entirely unproblematic but given a choice between “Europe” and “Asia”, I definitely wouldn't look for it under “Asia”.
Incidentally, many (US) companies have “EMEA” operations (i.e. Europe-Middle East-Africa) that are entirely separate from their Asian branches, which makes a lot of sense to me. Some websites have categories like “Middle East” because the region does not entirely “belong” to either Europe or Asia, this could be a practical solution.
After reviewing the diffrent answers and comments I've decided that the best course of action is to open a new answer titled "The Middle East" where Israel belongs.
This, in my view, is the best course of action as it suppurates Israel from Europe, and from the far east.
Hopefully that with time information for other countries from the Middle East will be added there as well.
*-This answer comes because even though I posted the answer (on the main site question) almost half a year ago, comments and answers on this meta question keep appearing.
Israel takes part in Eurovision, so is Europe by that definition...
If it were me, I'd probably put it in the Europe section for now, but be ready to move it as and when we get entries for the likes of Turkey, and other countries from that part of the world.
