Some recent poll data from the Peace Index:
Has the time come to annex?:
...We asked: “Next year will mark the 50th anniversary of the Six Day War. Some claim that the time has come for Israel to formally annex all the territories conquered in the war that it still holds. Do you support or oppose this?” In the Jewish public we found 45% favoring annexation and exactly the same rate opposing it.
Continuing the occupation:
A considerable majority of the Jewish public (61%) opposes the view that: “The Israeli-Palestinian conflict is perhaps not ideal but can continue for many more years without posing a threat to Israel’s security and existence.”
Occupation and democracy:
A clear majority of the Jews (66%) disagree with the claim that the ongoing control of the territories prevents Israel from being a real democracy.
