If Ariel Sharon were able to hear the news from the Gaza Strip and West Bank, he would call his loyal aide, Dov Weissglas, and say with a big laugh: "We did it, Dubi." Sharon is in a coma, but his plan is alive and kicking. Everyone is now talking about the state of Hamastan. In his house, they called it a bantustan, after the South African protectorates designed to perpetuate apartheid.

Just as in the Palestinian territories, blacks and colored people in South Africa were given limited autonomy in the country's least fertile areas. Those who remained outside these isolated enclaves, which were disconnected from each other, received the status of foreign workers, without civil rights. A few years ago, Italian Foreign Minister Massimo D'Alema told Israeli friends that shortly before he was elected prime minister, Sharon told him that the bantustan plan was the most suitable solution to our conflict.

The right and the settlers feared that the disengagement from the entire Gaza Strip was no more than a down payment on a withdrawal from most of the West Bank. The left and the international community similarly believed that if the evacuation of Israeli soldiers and civilians from Gaza went well, the way would be paved for a two-state solution; but there were also some who feared that Sharon did not intend merely to sever Gaza from Israel, thereby erasing 1.4 million Arabs from the demographic balance, but also to drive a wedge between Gaza and the West Bank.

Exactly two years ago, in June 2005, Egyptian Foreign Minister Ahmed Aboul Gheit warned Shimon Peres during a visit to Israel that if the disengagement were not accompanied by progress toward a solution in the West Bank, the Gaza Strip "would explode," in his words. The then vice premier told his guest that he agreed with every word, but took care to point out that his statements did not necessarily reflect the views of prime minister Sharon.

Israel's violation of the Agreement on Movement and Access, which was signed by U.S. Secretary of State Condoleezza Rice, strengthened suspicions that Sharon was plotting to sever Gaza from the West Bank. The order that the dogs could bark, but the caravans would not move between the Palestinian Authority's two sections had already been quietly issued by the end of 2005. That was a few months before Hamas' victory in the PA parliamentary elections provided the winning excuse for sealing off Gaza. Following the political upset in the territories, the severance policy became official. Israel imposed a sweeping ban on Gaza residents entering the West Bank, which even applied to students with no record of security offenses. Even as it was protesting the Hamas government's refusal to commit itself to previous agreements, Israel was disavowing the interim agreement (Oslo II) that it signed in Washington in September 1995, under which the West Bank and Gaza constitute a "single territorial unit."

Alongside the severance of Gaza from the West Bank, a policy now called "isolation," the Sharon-Peres government and the Olmert-Peres government that succeeded it carried out the bantustan program in the West Bank. The Jordan Valley was separated from the rest of the West Bank; the south was severed from the north; and all three areas were severed from East Jerusalem. The "two states for two peoples" plan gave way to a "five states for two peoples" plan: one contiguous state, surrounded by settlement blocs, for Israel, and four isolated enclaves for the Palestinians. This plan was implemented on the ground via the intrusive route of the separation fence, a network of roadblocks deep inside the West Bank, settlement expansion and arbitrary orders by military commanders. The cantonized map that these dictated left no chance for the road map or the "gestures" that Israel promised to PA Chairman Mahmoud Abbas and the Americans.

But the hope that Hamas' thugs and Fatah's good-for-nothings will finish the work of that well-known righteous man, Sharon, and his flunkies in the government and army is no more than a warped delusion. Eight years of rioting and terror ended in the liquidation of South Africa's bantustans and their inclusion in a unified state governed by the black majority. This dream of Palestinian protectorates - Hamastan in Gaza and the Fatahland enclaves in the West Bank - is similarly the end of any solution based on dividing the land: Israel in agreed-upon borders based on the Green Line and Palestine on the other side. If we do not quickly wake up from this dream and rescue what remains of the two-state vision, we will truly be left with a choice between the plague - an apartheid regime - and the cholera: the Jewish state's replacement with a binational state between the Jordan River and the sea. Including the Gaza Strip.
