Except Greater Israel was never a thing biblically, they had no plans of extending their territory beyond what God had given them, and most of the time often couldnt even hold that much. I think the greatest extent of Israel as a unified Kingdom was under Solomon, after which point it split into two competing kingdoms, Israel and Judea. This Greater Israel thing is a kabbalistic plan to usher in anitchrist, they LARP as jews because if they showed their true faces, even the goodest goy dispensationalists would be lining up to glass Isntrael back to the stone age.
