A lot of effort goes into hasbara to try to convince people around the world to think more positively about Israel. However, how much effort goes into trying to determine what messages have the desired effect of inducing more positive opinions of Israel? Many on the right assert that the key is not to be too mealy-mouthed by constantly issuing qualifiers, such as restricting it to internationally recognized Israel, on such support. Are there any examples of anyone not already a supporter of Israel being convinced to support Israel by a no-apologies defense of Israel?
As far as anti-Zionists being convinced to support Israel, I am aware of two examples. The first one I learned of was Kasim Hafeez, a British-Pakistani Muslim who grew up with the stereotypical Muslim attitude towards Jews and Israel. His path to embracing Israel started with purchasing Alan Dershowitz's The Case for Israel, with the intent of fisking it, then discovering that his upbringing provided no answers for what was there, and decided to find out for himself where the truth is. The second is Hunter Stuart, a journalist who grew up in a typical liberal New England home where it was taught as self-evident that the Jews in Israel were European usurpers of Palestinian land. One of the critical items in changing Stuart's mind was meeting Mizrahi Jews and learning about the Jewish refugees from the Arab world, before which he believed that all Jews were Europeans.
If we're going to be effective at hasbara, it would help to identify a larger sample of people who changed from hostility towards Israel to support and look for common threads between what changed their minds. While there is a lot of material in The Case for Israel and there was more to Stuart's epiphany than meeting Mizrahi Jews, the standard hasbara is not what has convinced them. However, it does suggest that telling more of the Mizrahi story would increase support for Israel.
