The most logical vehicle for this redefinition and hence for the solution to the Palestine problem is the kingdom of Jordan. Over the last seventy-five years, Jordan has developed into a relatively well-governed state, although the impact of regional political turmoil has caused it to fail economically and become heavily reliant on foreign aid for its survival. It is this Jordanian governance infrastructure that needs to be captured and put to productive use in integrating the millions of Palestinians and Jordanians into a modern, reasonably well-functioning state that would, in an era of real peace and economic integration with Jordan’s neighbors, have a much higher chance of growth and prosperity.
This proposed enlarged kingdom would include present-day Jordan, Gaza, and the West Bank (areas populated by Palestinians attached in a contiguous manner and physically connected to Jordan, i.e., not broken up into islands). Israeli arguments as to the need to retain the Jordan Valley become moot since the valley will now be controlled by a Jordanian government with a reliable record of maintaining peace with Israel. The convenient argument that Israel has no “peace partner” will now also be eliminated.
Jerusalem, despite the fact that neither Arabs nor Muslims have a hope of dislodging Israel from it, is, given its symbolism, a key bargaining chip in Palestinian hands. The formal relinquishment of any claims to Jerusalem (with an appropriate arrangement for the holy places) can be an important concession used to secure the foregoing terms. The Palestinians, after all, are the only party who can do this and, hence, completely legitimize Israel in the eyes of the region and the world.
Palestinians in Arab countries like Lebanon can then become citizens of this enlarged kingdom while also getting full residency rights in Lebanon, equivalent to what an EU citizen has in the European Union outside his or her home country. This would allow the Palestinians to gain full civil rights as legal foreign residents without impacting the local political or sectarian balance in these countries. The GCC, the EU, the US, Canada, and others can also help support this solution by granting this Jordanian–Palestinian passport easier access to their labor markets.
