The two-state solution in Palestine may have been a viable solution back in 1947/48. But the farther it got from the time of its ideation less and less it became a real possibility. Many U.S. administrations and other government, including some Israeli cabinets, paid lip-service to the idea but nobody could possibly believe in earnest that such an eventuality will ever come to pass. For one thing, consider the geographical divide which is the Negev desert, separating the Palestinian population in the West Bank from the Palestinians in Gaza. Historically, such bifurcated countries have not worked out. Exhibit A: East and West Pakistan, with India in between. Eventually the two parts of one shall separate. Exhibit B: The ill-fated administration of the Portuguese enclaves on the Indian subcontinent, with India controlling the lines of communication among them. On the basis of these two exhibits I concluded a while back that the solution to the Israeli-Palestinian conflict was not a two-sate solution but perhaps a three-state solution, with Gaza becoming its own country, and the West Bank becoming another.

In the recent demonstrations on U.S. college campuses one often heard the slogan “From the River to the Sea,” implying that the liberation of the Palestinian people in Palestine required that their homeland stretch from the River Jordan to the Mediterranean Sea, with the subtext that therefore Israel should cease to exist. This chant was an echo of the sounds of yesteryears when the Arabs in the Middle East chanted for the throwing of the Jews into the Mediterranean. Those who condemn the call of “river-to-the-sea” as anti-Israeli and (unfairly) anti-Semitic, shamelessly ignore the policies of successive Israeli governments (not just Netanyahu’s) in promoting the creeping acquisition of Palestinians’ lands on the West Bank through tacit or express approval of illegal settlements. If left to the current trends, Israel in a matter of a few years would indeed have accomplished its own version of the “river-to-the-sea” scenario – from the sea to the river!  

Whether Israel withdraws form Gaza or not, the slaughter of tens of thousands of civilians and destruction of lives and infrastructure will fuel greater visceral hatred of Israel and (unfairly) the Jews on the part of those Gazans who were lucky enough to survive.  In the West Bank, the actions of the Israeli government and Israeli settlers will continue to inflame the resentment that the Palestinians already feel toward their occupiers. And, now, with the extensive Israeli bombardments of Lebanon and the killing of civilians, Israel can add to its list of enemies the Lebanese too! Even if one day a new Israeli administration were to show interest in a two-state solution, the Palestinians and the Arab street would not go along with it – insisting, as some pro-Palestinians have already, on a homeland form the river to the sea.”
