Dutch author Leon de Winter talks with SPIEGEL about his new novel, which is set in 2024, the threats mounting against Israel and the assimilation of Muslims in Europe. SPIEGEL: Mr. de Winter, your new book — “The Right of Return” — is a novel, but it actually describes a political vision. In the book, it is the year 2024, and Israel has shrunk to just a few square kilometers around Tel Aviv, which is surrounded by enemies. Are you simply playing with some ideas here or is this a serious prediction? Leon de Winter: Both. Israel is menaced by two threats. On the one hand, by the hatred of its enemies, which today is primarily stirred up by Iran, and on the other hand, by the erosion spreading throughout Israeli society. There are three groups that have little in common: the Orthodox Jews, the Israeli Arabs and the secular Jews, who currently make up the majority of the population. But this majority is dwindling. The conflict between these three lifestyles is every bit as much of a threat — if not even more dangerous — to the existence of Israel as its outside menaces.
