"In an interview for the documentary, In Israel: Ministers of Chaos, produced by European public service channel, Arte, [Israel's Finance Minister Bezalel] Smotrich claimed that Israel would expand “little by little” and eventually encompass all Palestinian territories as well as Jordan, Lebanon, Egypt, Syria, Iraq, and Saudi Arabia."

This is a minister who is very powerful in the current Israeli government. To dismiss this is pretty weird. He doesn't hide his ambitions.
I am actually agreeing with him that this is likely to try to happen least for the foreseeable future. The trends point in this direction.
