Why is it permissible (or is it permissible) to live in communities in the West Bank that are situated in very dangerous areas even if it constitutes a danger to your own life and the life of your family? Does the mitzvah (if there is a mitzvah) of settling in the these far-out settlements somehow overrides this concern?
Interestingly R Shlomo Aviner writes this is a very old question.
At the end of the Kuzari [written in ca. 1140], the King of the Khazars asks the scholar: “Why are you going to Eretz Yisrael? Surely the trip there, involving travel over land and by sea, is fraught with danger?” The scholar responds, “It is no different from the merchant who travels far in hope of earning a profit.”
We must to distinguish between cases of “harm being common” (Pesachim 8b), where we have to be cautious, and cases of “harm not being common,” where we need not be cautious.
There have been 88 casualties from terrorism in all of Israel (not just the West Bank) between 2012-2016 compared with 1633 from road accidents. As such terrorism falls into the harm not being common category.
