I guess I was wrong. It is about the money, though perhaps more about the principle of people like Doherty having to buy life insurance but then not getting anything back from that policy.
If the insurance is able to keep from paying up because the death was considered the result of an act of war, then is the Doherty family suing for Doherty being in a war zone that was only equipped as if it was not a war zone? (IIRC it wasn’t equipped/protected enough to even be a consulate or outpost, much less to be in a war zone).
