Insan,
I think I understand what you propose about property rights, and it still seems to me to be too open-ended ...
Everyone hated the Annan Plan because it was too vague, but what you propose for property rights is even more vague than the Annan Plan. You are saying that the Solution itself should have no provisions as to how to resolve disputes between current tenants and legal owners, and people should simply fight each other in court when the problem arises ...
I think the whole point of striving for a comprehensive settlement, is that such issues should be clearly resolved in advance, so that everybody knows exactly what they are getting into ...
I suppose there is room for disagreement as to how to balance the rights of current occupants with those of legal owners in a future Plan (Magikthrill obviously has a different opinion than myself, for instance), but whatever the final balance I believe that it should be clearly spelt out in the Peace Plan, so that, when people are voting to accept or reject the proposal, they will know exactly what they will and what they will not be getting.
