I have no doubts that Israel is willing to search for support anywhere it can find it. Yet, this doesn't mean that they don't need the western one to keep with their standards of living, political standing in the west, and self-identification as a modern western country. A serious political condemnation and sanctions would be enough to steer Israel towards a different course- provided that the radicalisation of society hasn't already reached a point of no return. On the other hand, the US certainly doesn't need an ally that creates far more problems than it resolves. Their solid, oil-rich ally in the region is Saudi Arabia. The power dynamic between Israel and the US is not that of a client-state and its powerful protector or even one between allies; it resembles more that of a narcissistic, abusive lover towards their submissive partner. This is why we have been seeing the entire US government utterly humiliating itself for the past few months, finding pathetic excuses to pretend they haven't been slapped in the face every single day, while reiterating their unconditional love and swearing that their partner never did anything wrong. Really, there is no rational (in the sense of geo-political or strategic) explanation for this. It's a psychological subjugation.
