There is a reason why most refuse to answer the question was Egypt desolated for 40 years by Babylon. If you say yes then you have disproved 587. But if you say no, like auldsoul has, then you have contradicted Jehovah. You certainly can't admit that JWs are right about 607, but you certainly don't want to outrightly contradict Jehovah although auldsoul had no problem doing just that. So you are in a dilema when it comes to answering the question.
So here is what we have:
Did the 40 year desolation of Egypt take place?
JWs say yes because Jehovah said it would.
587 proponents say no because there is no secular evidence and so they invent outlandish reasons why Jehovah's word was not fulfilled.
Jehovah's word or secular evidence? Which do we accept? Yes, it really is just that simple.
That is why the 40 year desolation is being discussed on a 607 thread. But Tyre being rebuilt or not could only need to be discussed here if a person is trying to show that the Bible and especially Ezekiel is unreliable.
