The Palestinians have always refused to talk to the Israeli's to negotiate land , which Israel had suggested by having two states, Palestine and Israel, but as things stand Israel are the sovereign rulers.
There'll never be peace until a two-state solution is adopted, though you now have Hamas who are resisting any effort to bring peace and establish two nations living side by side----Palestine and Israel, in harmony.
It's not all Israel's fault if you read up about this complex situation which began hundreds of years ago when the Christian Romans massacred thousands of Jews.
Hamas are the problem. A Palestinian militant organisation who want to create an independent Islamic state in Palestine.
