This isn’t just a matter of vague speculation as there are historical cases outside of Israel on which to see how things like this develop and what the consequences are both for the victims and the soldiers. These historical accounts also indicate soldiers committing these sorts of actions become victims themselves with catastrophic mental health disorders.
Israel got in trouble with ICJ court, because of quotes from top government officials. Government of Israel was very specific what they will do to Gaza! This was even full scale bombing started!
Trying to reinterpret this as a problem of "military discipline", and "soldiers are victim as well" is just another level of cynicism!
It's happened, many times. Usually this doesn't make front-page news, but soldiers that break the law are sometimes held accountable. Not nearly enough, and I think it should be far more publicized as a deterrent effect (the fact that it isn't is a pretty big indictment of the current government). But it's certainly not laughable.
A part of what the Isareli opposition has been pushing for in the last few years has been removing Netanyahu from power and presumably jailing him because of the corruption charges.
