That is the problem though, it doesn't satirize the source material.
It satirizes a strawman of the source material since it cuts out or alters almost every part of the book that does not support the movie's satirical objective.
I think that is what pissed a lot of people off who read the book.
If they wanted to satirize jingoistic mentality they could have done it without butchering the book by starting with a new IP (but then they couldn't have taken advantage of the "Starship Trooper" title.)
