'Greater "israel"' is a jewish biblical vision rooted in scriptures such as Genesis 15:18.
In mainstream jewish theology, the territorial covenant of the 'Promised Land' belongs exclusively to jews.
This includes Palestine, Jordan, and parts of Lebanon, Syria, Iraq, Egypt, and Saudi Arabia.
The realisation of this vision would involve the murder and or displacement of at least 60 million non-jews, specifically mostly Muslim and Christian natives.
This equals to 8 murdered or ethnically cleansed non-jews for every 1 jewish resident.
It would create the largest refugee crisis in human history.
All of this is based on an interpretation of jewish scriptures that no other nation or religion agrees with.
This is religious supremacy.
