Technically, yes, although on reaching the age of 120 your Israeli Will would then need to be probated in more than one jurisdiction, which can be a costly and bureaucratic procedure.
As a general rule, a person who owns assets in different countries or jurisdictions, is therefore advised to prepare a separate legal Will in each jurisdiction, in order to avoid unnecessary tax and other complications in the future. So, if my wife and I own assets in Israel but we still own assets in England and America, between us we should sign three separate wills: one in Israel and in the UK for me, and one in Israel and the US for my wife.
