English, Ethics in Literature

There needs to be answered to a following question in a form of discussion.

Much of the stories in O’Brien’s novel The Things They Carried are imaginative reinventions of actual episodes that occured during his own tour of duty in Vietnam in 1968-69.  For O’Brien, happening-truth (what actually happened in real life) can be less true than story-truth (what happens only in fiction). Do you agree with O’Brien’s artistic philosophy?  Why or why not?

Can someone help me please?
