There are already Jewish towns in Palestinian territory. They're called "settlements," and they're populated by violent religious fanatics who believe that the West Bank is their promised land.
As for why I criticize Israel, it's because I believe that no government and no country should be above the law—not the United States nor my own country, not Russia, not China, not Saudi Arabia, not Iran, and not Israel. And above all, I criticize Israel because, in doing so, I'm hoping to expose the soft antisemitism of low expectations.
