A thought-provoking argument that I read recently was that Israel's relationship with the diaspora has undergone a fundamental shift in the last 20 years, largely tracking with demographics: it's no longer the case that Jewish life is primarily diasporic in nature, and Israel's growing impatience (and sometimes open disdain) for the diaspora tracks with that demographic reality.

I think this is an underrepresented factor in why Israel feels unilaterally emboldened in this conflict: there's no longer a statistically more liberal, secular, identifiably Jewish majority outside of the country that serves as a check on its actions.
