This is a popular quote. But, not so true in the past couple hundred years. WWI were cousins and uncles of royalty fighting. WWI was a psycho Hitler trying to rule the world. I don't know what Korea was about. Vietnam was over rubber trees because of the great explosion of automobiles. Desert Storm was over oil.
That's why you didn't see any Nazi symbols nor any Asian symbols on the 223 round , and desert storm, well that wasn't a war that was an invasion .
