For the ideology of settler colonialism, the impossibility of concretely imagining a decolonial future ought to serve as a warning sign. It is possible to look forward, in general terms, to a future in which the United States disappears and indigenous life continues. But it is hard to envision getting from here to there without destruction and suffering on such a vast scale that even the partisans of decolonization refuse to discuss it. Israel is much younger and smaller than the United States, and it is easier to imagine its disappearance, but again, not without massive death and destruction.
