It should have been tried at least. Israel didn't try to speak with the Palestinians. Though I once talked about it with my neighbour in student dorms, when I was in the university. He was a very educated, religious and nice Palestinian guy, who studied medicine in Jerusalem Hebrew University. And I said what is written in this article: Israel should have proposed two-states solution back then in 1967. He responded: "What you're talking about? Back then there was nobody, who could possibly accept it, nobody, who could recognize Israel." But it might be just his opinion. Anyway, it should have been tried then.
