Greater Israel can't ever exist and its more an anti-semetic conspiracy theory (with all due respect). The entire region and world would turn on them if Israel tried to implement it, and frankly, many of our Government say badly worded or out of context statements all the time but they're not considered official policy.
Israel wants to protect itself. Yes, they do horrendous shit to achieve that goal, but they're not an imperialist force that is trying to conquer countries. They're cunts, but not that type of cunts. The state of Israel is bad under Bibi because their doctrine has become "survive at all cost", not "expand at all costs". There's a moral difference there. I'm no fan of the Israeli government but I can recognise the difference between desperation and imperialism
