Israel’s critics today like to argue that the country is illegitimate because it is the product of what they call settler colonialism. They consider non-Jewish Arab peoples the native inhabitants of the land—inhabitants who were displaced by the appearance of Jewish immigrants over the last 150 years. The great colonial moment was capped in 1948, when the Jews established political sovereignty in the state of Israel; then, subsequent wars, including and especially the Six Day War of 1967, further expanded and entrenched that moment. According to this sort of analysis, Israel is always and forever illegitimate. Much the same is seen as true of America, which was not only illegitimate at the moment it seized native lands, but is still illegitimate, and will always be illegitimate. This dynamic is captured in a comment by Patrick Wolfe, a frequently quoted Australian scholar of settler colonialism: “invasion is a structure, not an event.” This worldview establishes a moral hierarchy, draws political alliances, establishes political adversaries, and has been at the root of the ideological assault on Israel and its allies. It’s an idea that the critic and writer Adam Kirsch explores in his new book, On Settler Colonialism, published recently by W.W. Norton & Company. Here he joins host Jonathan Silver for a discussion of his book and the controversy around Israel.
