(1933) drew an analogy between the return from Babylon and the early waves of immigration to Palestine. Lieberman also published utopian novels. Khalom ha-shlosha (“The Dream of Three), for example, is about three friends from the city of Safed, one of whom cares only about money, and another, only about having fun. Both are saved from a life of sin and wastefulness by the third friend who establishes a socialist commune. Some of Lieberman’s books were translated into English. Science Fiction ’Tevel betkhiyata תבל בתחיתה (Renaissance of a Universe) (1955), about a utopia built by astronauts on a trip to Mars, was one of the first science fiction books written in Hebrew. In the future foresaw by Lieberman, a Third World War leaves the whole world terribly devastated, but strong-willed reformers, led by Jews from Israel, oversee the reconstruction, ensuring that the rebuilt world be united under a benevolent world government - aided by Progressive, ecumenical-minded religious leaders who eventually unite all world religions into a single faith. Centuries in the future, the prosperous Earth embarks on the great venture of sending a massive spaceship, with a hundreds of a well-equipped crew, to Mars. They find Mars inhabited by humans similar to those of Earth. Politically the planet is divided into two mutually-hostile Empires, both militarist and highly oppressive to their subjects. The visitors from Earth are especially concerned about an ethnic group called the Yonodins, who live in scattered communities all over Mars and are everywhere subject to racist prejudice and persecution; a Jewish crew member intervenes to prevent a pogrom of Yonodins. While formally keeping cordial relations with the Emperor hosting them (who hopes to gain advanced Earthly weapons for use in his next war) the visitors from Earth decide to secretly intervene in Martian politics and sponsor the creation of an underground organization aimed at overthrowing both Empires. The conspirators are led by a highly capable Yonodin woman, the love interest of the book's Jewish Israeli protagonist. Eventually the two rival empires embark on an all-out war with each other, which might leave Mars devastated as Earth was centuries earlier. However, the underground manages to infiltrate both armies. Eventually soldiers mutiny en masse, end the war, overthrow both Emperors and unite Mars. In the happy end, Mars gains a world government modeled on Earth's, with the protagonist's beloved as its First President. Published works Ha-dayagim ha-ktanim, 1932
