If your going to pretend like Israel wasn't directly only able to be established without going through the British, who have nothing to do with the land. And that in order for it to be established a massive ethnic cleansing, removing Palestinians for their land, didn't happen. Then you can stop right there. You're not dealing in reality and it's a complete waste of time to even engage you.
If you agree instead that those things are true, which they are. Then there's also nothing to talk about. This idiotic questioning about a Palestinian state is irrelevant. No one says America wasn't stolen because native Americans didn't have an established state. Which is why your question is stupid. It's just an attempt to feel better about what is clearly and thoroughly criminal. No matter how many books you point to that say it's a chosen peoples land.
