Answer:
Goines uses satire in his narrative because he wants the reader to think critically about the war.
Step-by-step explanation:
Satire is a literary or artistic technique that ridicules a particular theme, usually as a form of political intervention or otherwise, with the aim of provoking or avoiding a change, but the purpose of satire is to make the reader reflect and think critically in a particular situation .
For this reason, in "Let Sleeping Dogs Lie" by David Lance Goines, he satirizes the journey he had to avoid recruitment during the Vietnam War. The purpose of this work is to make the reader think critically about war.
