I lived in Nigeria during a period of violence when thousands died.  One of my enduring memories was the reactions of the Americans living there at the time.  They were so sure that the army would come and save them and when it didn&#x27;t they were dumbfounded.  When someone from the US eventually turned up after the violence had all died down all the US citizens were offered was the opportunity to be part of the convey out of the city.<p>I wonder where the dead set certainty that the army will save them comes from?
