I would absolutely put "Israel taps the National Security Advisor's phone" in a different category of risk to the two country's relationship than previous activities. This, again, isn't a normative argument.

(A piece of context that's often missing from - typically charged - discussions about US/Israel relationships is the degree of dependence between the two, and how that's varied over the years. Israel's defense policies have historically been informed by a desire to be fully self-sufficient during wartime, i.e. not require active support from countries like the U.S. That policy has been deprioritized over the last 20-30 years, to the point where the US is now a significant active defense provider for Israel, rather than just an arms supplier. This is a dependency relationship that's new to the ongoing conflict, and should color any analysis of Israel's willingness to do things that would threaten its relationship with the U.S.)
