How do people expect the world to help with tragedies? (Night Book)

I think one of the themes of the book involves the world's collective abandonment of Jews during WW2. This lack of compassion has not changed since. Every few years there are wars and genocides, which fortunate countries in the world, if it is not in their interest, largely ignores. It took, for example, the picture of a dead boy washed up on a Turkish beach to make the world pay attention to the plight of Syrian refugees. So I suppose the answer to your question is that people cannot expect help from the world in times of intense strife.
