Found the following article online, use it to answer the question: What did Hans Müller think would prevent tragedy befalling he and his family?  After World War II, a German named Hans Müller is one of a shipload of Jewish refugees who disembark at Haifa in 1949. Like many other concentration camp survivors, Hans has psychological problems, including survivor guilt. At one point, he mistakes a woman and some children for his murdered family. At the first opportunity, he sneaks out of the refugee camp and goes into the city. When he spots a policeman, Hans panics and reacts by fleeing. The policeman chases him down and begins questioning him. Hans becomes very agitated and attacks, leaving the man unconscious in the street. Hans flees and ends up sleeping in the countryside, where he is found by a teenage orphan Sabra, Yehoshua "Josh" Bresler. Hans pretends to be an eccentric American, out to see Israel firsthand. Josh offers to be his guide. During their journey, Hans reveals that he was a professional juggler; Josh persuades him to pass on his knowledge. Meanwhile, police detective Karni sets out to track the fugitive down. On their journey, Josh is injured when he wanders into a minefield. He is taken to a hospital at a nearby kibbutz, but has only broken his leg. While Josh recovers, Hans becomes acquainted with one of the residents, Ya'el (Milly Vitale). They are attracted to each other, but he at first strongly resists her attempt to persuade him to remain at the kibbutz. He reveals to her that he had ignored warnings from friends to flee Nazi Germany before it was too late, making the fatal mistake of counting on his fame and popularity to protect his family. Gradually, however, he begins to settle in. Karni finally tracks Hans down and tries to take him into custody. Hans panics again and barricades himself in Ya'el's room with her rifle, but Ya'el and Karni get him to admit he needs help and to give himself up.

his fame and popularity
