I have a post coming for the 75th anniversary of the Iwo Jima landings set to come out next month. I also watched the companion movie to Letters (they were made simultaneously) Clint Eastwood made in 2006 – Flags of Our Fathers. So you had 2 movies of Iwo Jima – from the perspectives of both sides.
It is all too easy to lump a wartime enemy into “they” with monolithic stereotypes and behavior.
