Everybody from Rabin - Olmert & Bibi have been in favor of trading parts of Israel with large arab population centre's to the palestinian state in exchange for land with very few arabs then the arabs now in the palestinian state would trade their Israeli citizenship for citizenship of the palestinian state. So its possible Bibi may like the idea of trading the fertile Jordan Valley for parts of the fertile lower Galilee region where there is the arab triangle. We both get fertile land but Israel looses a large percentage of its arab population and nobody looses their homes etc they just trade citizenship which is not a new concept and Israel would not be the first country in the world to do something like this.
