Few Jews are likely to immigrate there if security concerns remain acute and the cost of living continues to rise. Conversely, many of the country's most talented and internationally mobile citizens may choose to leave unless they are deeply committed ideological Zionists prepared to endure a permanently militarised society. Seeing Nazis behind every threat is not healthy. It risks becoming a form of historical paranoia. While anti-Semitism certainly still exists and should never be underestimated, the crude, genocidal anti-Semitism of the Der Stürmer variety is not widely held in the liberal democracies to which many Israelis might emigrate. There is also the unresolved question of the Haredi population. If large numbers continue to neither participate fully in the workforce nor serve in the military, while maintaining high birth rates, the economic and social burden may become increasingly difficult for the state to sustain. Studying the Torah is a noble pursuit, but as a governing economic model it is difficult to see how it can support a modern nation-state indefinitely. Even Iran's clerical establishment, for all its ideological rigidity, oversees a society in which most citizens work and contribute economically. That distinction may become increasingly important as demographic pressures intensify.
