Historically, Palestine was divided into two territories. A sliver for the jewish palestinians, which was renamed “Israel”, and the remainder for the arab palestinians, which was renamed “Jordan”.
Jordan is arab palestine, and Israel is jewish palestine.
In other words, there already is a two state solution; the two states already exist. The only question is what to do with the arabs on the land that Israel won from Jordan during the 1967 war. The answer is not another independent arab state; such a state sandwiched between Israel and Jordan is not viable as an independent state. There will never be an independent arab west bank, quite simply because it is not viable. It has no independent economy, no markets, no jobs, no nothing that allows it to exist separate from Israel or Jordan.
Its future needs to be worked out between Jordan and Israel. No one else has any standing in the question. Israel should not treat the PA as a national entity, nor should anyone else, because it is not and never will be.
The only reason that Jordan maintains any credibility of civilization is the absence of the massive ‘Palestinian’ population Jordan rejected decades ago. Should the Hashemite King allow the ‘Palestinians’ to be integrated into Jordanian civilization that civilization will cease to exist. The Arabs have cultivated the backwardness of the ‘Palestinians’ and sustained their poverty as the Arab solution to avoiding absorption of these primitive people.
