[Genocide] refers to a coordinated plan aimed at destruction of the essential foundations of the life of national groups so that these groups wither and die like plants that have suffered a blight. The end may be accomplished by the forced disintegration of political and social institutions, of the culture of the people, of their language, their national feelings and their religion. It may be accomplished by wiping out all basis of personal security, liberty, health and dignity. When these means fail the machine gun can always be utilized as a last resort. Genocide is directed against a national group as an entity and the attack on individuals is only secondary to the annihilation of the national group to which they belong. 1946. Raphael Lemkin
I can easily see arguments that this situation is not applicable here. Israel stated goal is security, return of the hostages and Hamas destruction. (Hamas on the other side openly state destructions of Israel and Jews "from the river to the sea" as its one of the main goals, i.e. actual genocide). None of this fits into above definition. And while it is true that there are members of parliament from ultra right that want to do ethnic cleansing (but not genocide) this is not official position.
So, again, I will argue that calling this complex situation genocide is an easy political point scoring. Does not help discussion of the actual problem.
