Jay Currie over at TCS has an idea for at least temporarily solving the demographic threat (this article is also referenced on his blog here):
If the demographics suggest a situation in which the Arab population will overwhelm the Jewish one, Israel could take the option of offering what amounts to non-resident citizenship to Jews worldwide. A generation ago this would have been practically impossible: the paperwork and the sheer expense of processing millions of new citizenships would have been unmanageable. Now, a relatively simple, secure internet driven, virtual citizenship program could be created in a matter of weeks.
This idea has been thrown around before in various forms, but the fact is that Israel is very reluctant to let even citizens that live overseas vote. The reason is relatively easy to understand: Jews overseas don’t have to live with the consequences of their votes. So they can afford the luxury of, for instance, opposing concessions for peace – say, Palestinian rights to East Jerusalem. Israelis who actually have to live with the day to day horror of suicide bombings, on the other hand, might find such concessions reasonable. And they should be the ones who get to decide.
