I disagree that this is the turning point tho.

Turning point, no, but I can see this being, in retrospect, an erm fulcrum point. Like what 9/11 did to the US, where the question "why do they hate us", besides further idiocy, also led to some legitimate insight into how the US' actions affect the world and provoke reactions, similarly the notion "we bred that monster" might get some more wide-spread traction in Israel.

...and yes this very much is a 9/11 moment for Israel, worse, actually. Caught completely on surprise, the most Jewish deaths and that in a short time-span since the Holocaust, much larger percentage of the population, it's definitely a defining moment.
