Trying to remember the books ending....
Was it a realization that the PTB were keeping the wars going?
Johnnie is pretty much presented as a gee-whiz (but naive only to how the military works), “All-American” young man. The twist is he’s ethnically Filipino and can speak Tagalog: the native language of the Phillipines.
SPOILER ALERT FOR THOSE WHO WANT TO READ THE BOOK!
The last paragraph is when.....
The main character wonders if the reports of what they have accomplished will be given to his father in his father’s language,Tagalog, showing the main character is not a lily white as in the movie.
