Government and regime can always change. Post socialist countries convinced border guards, for shooting unarmed civilians, who were trying to escape across country borders. That was a crime even under socialist laws.
If Israel had regime change, new regime and majority of voters would be pro Arab... New government could actually enforce existing laws!
The idea Israeli government would hold anyone accountable is a laughable.
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!
