That'll never happen. One state for both? After all the pain, suffering, and death that zionists have caused to the Palestinians, Lebanese, and Syrians, I doubt very much they'd want to co-habitate with them.
Likewise, I don't think zionists will ever want to share their "God given" land with anybody else. No matter who it is, Arab or otherwise.
Israel was supposed to be a shining beacon of democracy and freedom in the Middle-East and we all see what it turned out to be. A fascist, judeo-ethnic nationalist state where if you're of the wrong religion or descent, you're nothing and have no rights.
It's wishful thinking.
The only solution that I can see is if we abolish Israel and give Palestine back to its people and allow Jewish immigrants to move there and gain Palestinian citizenship as it was and should have been, before the first zionist colonist from Europe ever set foot there.
