In order to be both Jewish AND a democracy, the following conditions must be maintained: Jewish means governed by a Jewish-majority Knesset. Democracy means the government is elected by -and reflects the will of- a majority of the population. Therefore if the majority of the population became Palestinian, this would conflict because it infers the government elected would no longer be Jewish. The conflict can only be rectified by expulsion of sufficient Palestinians to resolve the population problem. Obviously this solution conflicts with the fundamental concept of democracy.
