True indeed. It lasted 8 years with a million casualties and an extensive use of modern weaponry but it was forgotten just like the Korean war.
I could advice you to read The Iran-Iraq War by Pierre Razoux or The Iran-Iraq War: A Military and Strategic History by Williamson Murray
There's this one by Pierre Razoux having an in-depth overview of the war and there's this one by Kevin M. Woods and Williamson Murray which uses a lot of unclassified Iraqi documents found after 2003.
This Reagan bio and this Iran Iraq war book are both pretty solid and touch on it

Pierre Razoux's "The Iran-Iraq war" is perhaps the best work on the subject. If that is too dry for you, Helion Publishing has a 4-part series on the war along with an upcoming series on the naval war. For the air war, Tom Cooper has a book on that but if you want more scholarly and reputable source then there is this from the USAF.
For a more personal feel on the ground, "I, Who did not die" tells the tale of an Iraqi and an Iranian fighting on opposite side, their chance encounter, and their separate experience as POW along with their attempts to go back to society. The story is so...miraculous that to this day a part of me still insists that this cannot be true and must be a work of fiction. But you be the judge.
First he's not an expert on the topic, he's a sociologist, second how do you trust a source you do not understand? Don't you see the clear fallacy. Third don't trust a random redditor, but trust actual historian or trusted sources, not some random sociologist finding conclusions that don't seem to add up (although I'm open to understand more, just need help which you can't provide apparently).
One of the most comprehensive and recent books on the war dedicates a chapter, "The Slaughter of the Child Soldiers" to Iranian child soldiers. https://www.amazon.com/Iran-Iraq-War-Pierre-Razoux/dp/0674088638
