Two points:
1) The most deadly attacks this year have taken place in undisputed areas of Israel, like Tel Aviv. While there are some kinds of terror more likely in the West Bank, by this logic, nowhere is really safe. The natural conclusion would seem to be, why would any Jews put their children in danger by living in this eretz ocheles yoshveha? And you see where that goes.
2) Everyone’s talking about people living in settlements like they’re all radical rightists moving there for ideological reasons. You do realize that Beitar and (IIRC) Modiin Illit are in the West Bank? Along with a huge portion of the charedi communities in Yerushalayim, where so many car attacks took place last year? It was enlightening being in Beitar for Shabbos among a bunch of chassidishe women who were simultaneously talking about the crazy settlers and being nervous about a two state solution which could theoretically put them out of the homes they’d made, mostly for neighborhood or financial reasons. And my personal closest scrape with any sort of terror was an infiltration across Beitar’s fence that occurred three houses from where I was staying. These aren’t radical extremists, these are people looking to live in places that are basically mainstream now.
