John and Jesus worked both sides of the Jordan river because the kingdoms of the Herods included that whole area. This is the paradigm of "Greater Israel", not just river to sea (Jordan to Mediterranean), but river to river (Euphrates to Nile), which includes several other sovereign nations nowadays. Israel's latest incursions demonstrate their perceived manifest destiny as growing into ability to manage this land again, as Solomon apparently did for a season. The prophecies indicate not that the world will fight Israel in a climactic war, but that designated powers will, not from Israel's local borders but from greater distance. This is why modern Israeli polity has always been fixated on control of relations with immediate neighbors so as to manage its ability to grow. There's a certain right for a tech state to have managed relations with its neighbors, but there's also an imperial risk that peoples join who don't have common interests (iron-clay) and create greater instability.
