I don;t think there is a sense that Israelis cannot be heroes. Israel does polarise international opinion because of its ongoing conflicts. But it is just one of many countries, its conflict is one among a number in the world and Israelis are human beings like anyone else. It must be very annoying to feel that the entire world is condemning you the whole time, but I don;t think that perspective is accurate anyway. Still, it goes to the heart of how some Jews feel that Jews and non-Jews are cosmically destined to interact. The very fact that some people feel that way changes the dynamics of any political situation.
