Solutions?
The primary approach to solving the conflict today is a so-called "two-state solution" that would establish Palestine as an independent state in Gaza and most of the West Bank, leaving the rest of the land to Israel. Though the two-state plan is clear in theory, the two sides are still deeply divided over how to make it work in practice.
The alternative to a two-state solution is a "one-state solution," wherein all of the land becomes either one big Israel or one big Palestine. Most observers think this would cause more problems than it would solve, but this outcome is becoming more likely over time for political and demographic reasons.
