I just finished reading Battle Cry, the novel about the Marines in WW2 fighting on the Pacific against the "Japs".
Is it money, real-estate, minerals? Wars are old as time, and there are a few going on right now.
Call me Gus, and perhaps I ask stupid questions, just the feelings after reading the book.
Wars are started for different reasons. Usually none of them good reasons.
But in WWII I believe there were very good reasons for that one.
As to Marines fighting Japs in the Pacific, you do recall Pearl Harbor, don't you?
