The Iran-Iraq war was one of the major wars of the 20th Century . Yet we don’t think about it that way because it was merely some back water cannon fodder killing each other. Half a million dead but the actual number is known only to God . That just shows how much either side cared about their own people. Tossed away in battle like so much trash.
One of the reasons getting rid of Saddam was a mistake, he kept the Iranians in check.
