For anyone who lived through the Holocaust, or who has relatives who died in it, being called a Nazi is unspeakably terrible. That is the secret weapon of the Arabs. Any time the Jews get wise and threaten mass expulsion of Arabs, the Arabs pull out their big stick, equating Nazism with Zionism. Their cartoons merge swastikas with stars of David. Their newspapers call Ariel Sharon another Adolf Hitler. Their spokespeople cry "Genocide!" And the Jews cower in fear that they could be equated with their parents' murderers.
The Jews don't realize that expelling a hostile population is a commonly used and generally effective way of preventing violent entanglements. There are no gas chambers here. It's not genocide; it's transfer. It's not Hitler; it's Churchill.
After World War II, Poland was recreated by the Allied Powers. In doing so, the Allies sliced off a chunk of Germany and extended Poland west to the Oder-Neisse line. Anywhere from 3.5 million to 9 million Germans were forcibly expelled from the new Polish territory and relocated in Germany.
British Prime Minister Winston Churchill was pleased with the result. In 1944, he had explained to the House of Commons that "expulsion is the method which, so far as we have been able to see, will be the most satisfactory and lasting. There will be no mixture of populations to cause endless trouble ... a clean sweep will be made. I am not alarmed by the prospect of the disentanglement of populations, nor even by these large transferences, which are more possible in modern conditions than they ever were before." Churchill was right. The Germans accepted the new border, and decades of conflict between Poles and Germans ended.
Arab-Jewish conflict is exponentially more volatile than German-Polish conflict ever was. And the solution is far easier. If there was "room in Germany for the German populations of East Prussia and of the other territories," as Churchill stated, there is certainly room in the spacious Muslim states of the Middle East for 5 million Palestinians and Israeli Arabs. If Germans, who had a centuries-old connection to the newly created Polish territory, could be expelled, then surely Palestinians, whose claim to Judea, Samaria and Gaza is dubious at best, can be expelled.
It's time to stop being squeamish. Jews are not Nazis. Transfer is not genocide. And anything else isn't a solution.
