Or just kick the Palestinians out of the West Bank across the border into Jordan and fill the vacuum with fresh Israeli settlers - thereby completing the Reconquista of Eretz Yisrael.
Its very anti-Semitic for you to suggest that Israel would engage in such a criminal act of ethnic cleansing, reminiscent of the Nazi plan to deport the Jews to the "Ost"...
Populations get kicked out of regions all the time; including a large number of such expulsions and transfers since WWII - the Czechs expelling the ethnic Germans in the Sudentenland, the Poles expelling the ethnic Germans in East Prussia, the Russians expelling and relocating minorities in the Caucauses, the Indians expelling Muslims during the split between India and Pakistan, the Pakistanis expelling Hindus at the same time, the Vietnamese dealing with their troublesome types, the Chinese dealing with Muslims, Mongols, etc. - and, of course, over 1,000,000 Jews expelled or nudged-out of Muslim countries in the 1948-1975 timeframe...
All of those since WWII, after the creation of the UN and much relevant international law - and none of those Semitic or anti-Semitic in nature - and none of them charged or prosecuted at-law as 'ethnic cleansing'; instead, pitched, and eventually accepted by fait accompli, as dealing with chronically hostile population segments in the only practical way; removing the danger they pose, while allowing them to live.
It is the only way to complete the Reconquista, and, if and when it comes, it will be no different any any of those other expulsions and transfers listed above.
Oh, and, by the way, the analogy to the Nazi variation on the theme only holds true if the Israelis start packing the Palestinians off to extermination camps and begin gassing them and bulldozing them into the ground en masse.
Without such intent and outcomes, the analogy is dismissed, with prejudice, and rendered into a much simpler and comparatively humane (non-slaughtering) Expulsion or Transfer similar in nature to those others listed above.
"...More likely, Israel wil just withdraw to their Plan B border, aka the Seperation Barrier."
Yes. So you have already said. We heard you the first time. But repeating it does not make it any more likely to happen, the 2nd time, or the 200th time, than the 1st.
