`  Uriber, I don't get your point about ``Chairman`` versus ``President``.  What difference does it make?  Even if there is a difference, what does it matter what the US and Israel use?  Would you mention it in the Sharon article if the PA ``didn't recognise`` the title of ``Prime Minister``?  Anyway, you are wrong about ``international documents``.  The example you gave is ``trilateral`` not ``international``.  If you go to http://domino.un.org/unispal.nsf and search for ``President Arafat`` you will find over 150 UN documents which use that phrase.   `
