(Resetting inserts). I guess the logic is a bit complex here. I am not disputing the fact that most countries do not accept Jerusalem as Israel's capital. What I am disputing is that most, some, or even any countries have made it an official policy to make Tel Aviv Israel's capital instead. I also accept the fact that in Egypt, the distinction between government policy and the press is very ehmm, porous, but I still haven't seen it stated as official policy by any sovereign government that "Tel Aviv is Israel's capital." My guess is that the publishers of the encyclopedia didn't want to write nothing about Israel's capital, and so said "Tel Aviv." 

 And there's a good reason for that. Countries that accept Israel's sovereignty must by necessity also accept Israel's sovereign right to establish a capital wherever Israel's government wants. Countries clearly have a problem with Israel's establishing their capital in Jerusalem for reasons that are beyond the scope of this article, but they have no basis to say "well, then it should be in Tel Aviv" or "it should be in Haifa" or "it should be in Ashdod." And countries that don't accept Israel's sovereignty wouldn't accept an Israeli capital at all. 

 You have only being able to pull out highly circumstantial evidence that the Egyptian government possibly considers Tel Aviv to be Israel's capital. This would lead us to simply omit any discussion of Tel Aviv in that context, unless we want to write something silly like "an encyclopedia published under the auspices of the Egyptian ministry of culture states that Tel Aviv is Israel's capital."
