Israel Arabs could become majority in 45-60yrs, quicker if E. Jerusalem Arabs decide to become Israel citizens and Right of Return must not include Arabs. A two state solution is not a option unless Israel Arabs move to new Palestine state. The settlements are pushing Israel to a one state solution but that leaves only Arab removal or an Apartheid system to keep Jews in the majority. The current path without a peace deal will lead to an arms race in the ME, possible nuclear and while Israel could win any war now in 10yrs with help of oil money that could change. There are atleast 4 Palestian group with different goals, the PA wants a state, Hezbollah/Jordanians wants RoR and Hamas I am not really sure. The root cause for all these problems is the desire and need for a Jewish Nation but the Jews will never give up on the ideal or dream of a new Temple in Jerusalem but the Palestian have a dream for a state and RoR which will be hard for them give up on.
