I believe most US Jews want deep down in their hearts to support Israel, it becomes harder and harder when the democracy you describe is crumbling. More and more we hear from the ultra-orthodox that if you don't believe as they do that you are not Jewish. Democracies treat ALL people equally and do not discriminate. Democracies follow international law. Democracies do not chastise their own because they do not believe as they do. If Israel wants the support of US Jews, they need to stop building in settlements and stop treating those who are not ultra-orthodox as a separate entity. Perhaps if Israel recognizes this they will have more US support.
