We can learn about the power of humor in difficult situations. Adrian Cronauer's radio shows in the movie, based on real events, showed how humor could lift the spirits of the troops during the Vietnam War.
From 'Good Morning Vietnam' we can learn several things. First, it shows the importance of human connection during a war. The radio DJ, based on a real person, was able to connect with the soldiers. Second, it gives us a glimpse into the cultural differences between the Americans and the Vietnamese during that time. Also, it shows how media, in this case radio, can be a powerful tool for communication and morale - building, as it was in the real - life story that inspired the movie.
