SPG have removed their brand names from the Moriah hotels (used to be Sheratons) because of disputes between the Moriah management and SPG and because the hotels were not good.
It also removed the Le Meridien brand from the hotel in Haifa (operated by Fattal).
OTOH, Hilton is building a new Waldorf=Astoria collection hotel in Jerusalem - the Palace.
The property in Tel Aviv (just north of the Hilton) has been linked to Hyatt for more than a century now but nothing really happens there and I would be surprised if something does happen.
