Israel has already achieved Greater Israel.
Israel doesn't want or need the physical land but, as long as the Arabs remain under its thumb, it effectively rules that landmass. The tinpot Arab dictators can live in their silly places and pretend that they are free and powerful, even as they watch impotently while their own race is slaughtered by the tens of thousands in front of them.
As for the non-Arab countries around Israel, Turkey is ruled by Erdogan who is nothing more than a drama dialog queen, and project Iran is underway to break it up as I described above.
As for Pakistan, we know India and Israel are coming for our nukes sooner or later. Hopefully we are prepared.
