A majority of Americans think Palestinians must acknowledge Israel's right to exist before they can have their own state, a recent poll commissioned by the Israel Project found. Though a large contingent believes in a two-state solution, 60% believe "there should not be a Palestinian state until Palestinian leaders end terror and recognize Israel's right to exist." 50% said they support Israel in the conflict, compared to 7% backing the PA. The poll also found that 73% of Americans favor international sanctions on Iran, even if it might lead to a 20% rise in gas prices. 71% believe that violence in the Middle East stems from clashes between moderates and extremists, compared to 18% who believe the Israeli-Palestinian conflict is the main cause.
