Israeli Jews are outnumbered by Arabs if you combine the Arabs in the West Bank, Gaza and Israel itself. Outside of that very small geographical area (Palestine) you are even more outnumbered by Arabs and surrounded by them. 1:60 ratio or something alike.
You have no options other than living with Arabs peacefully long-term. Talk about nukes etc. won't work as you will destroy yourself in the process and with how the times are moving, Arabs (Saudi Arabia prime candidate) will get nukes eventually as well if they don't already have them. It is old technology.
If your elites will not accept a two-state solution, you will live as a prisoner within a segregated golden cage always worrying about the next attack.
You have been living under the thumb of Arabs for centuries if not millennia and they never mass-murdered you and treated you better than the Europeans and others ever did. Food for thought.
Anyway are 50% of your population not Arab Jews?
