Israel cannot propose any sites beyond its recognized boundaries (see the problem with Tel Dan).
Is this correct?
I have re-read the published minutes of the 2011 WHC with regard to Tel Dan. We have already discussed this matter and established that the reason why Israel hasn't been successful with it has been the fact that a part of its buffer zone lies within a disputed area on the Syrian border.
The minutes however make it quite clear that the WHC was offered 2 options
b. Wait for "clarification" of the frontier.
Given the make up of the WHC (Iraq, Bahrain etc), the WHC opted for b (surprise, surprise...) - but, apparently it COULD have chosen option a.! There was no suggestion that such a decision to inscribe a site which was partly within a disputed area would have been ultra vires in relation to the Convention.
I have wondered why Israel thought it necessary to include this disputed area within the buffer zone of Tel Dan - was it being entirely "naive" on this matter or was it (surreptitiously) trying to get something past the system! There are plenty of inscribed sites on frontiers whose buffer zone should ideally extend into the neighbouring state. Of course, in such cases the buffer zone has to be truncated back to the frontier - i have never seen an Advisory body review stating that a site can't be inscribed because it should have a buffer zone extending into the neighbouring state! I have recently been looking at the boundaries of Al Ain (UAE). The core area runs in part along the frontier with Oman - in theory Oman could build a 100 story skyscraper or dig a mine or have a sand quarry etc etc in circumstances which, if the area had been a part of UAE, would not have been allowed.
On reflection - perhaps Israel was between a rock and a hard place - NOT to have included the disputed area within the buffer zone when it was natural to do so could have been taken as an admission that it did not "own" the area. "Giving" such things away outwith a negotiation is of course a diplomatic "no no"!
