Not to defend him on this per se, but this clip doesn't say what you are saying it says. Greater Israel is way more than just then the jews absorbing the west bank, it's an allusion to a land from the Euphrates to the Med and south and north into parts of Egypt, etc.

That Israel is so small and doesn't have oil compared to the rest of the Middle East is normie boomer propaganda that was big in the 1990s.
