Before '67, the territory was a part of Jordan.
Many have said there is a land for the "Palestinians" called Jordon. The proposal to annex the West Bank to Jordon is not far-fetched, for it has been seen at that by Arabs for decades now.
(Working in Israel was a wonderful time, from my perspective from those periods.)
Let's call the non-Israel West Bank what the Arabs called it for decades. Transjordan.
Jordan is awake country to begin with, and hostile to bout. It only occupied sanaria and judea by means of force. Invading Israel. It has zero legitimate rights to the land and will not be returning to any control over it.
