Or the Whisky War over Hans Island, which the Canadians claim and leave a bottle of (Canadian) whisky, upon which the Danish claim it and leave a bottle of (Danish) snaps, ad infinitum.
I think FabHK is referring to not the strategic advantage of "owning" that island but rather how that border-conflict is managed. Instead of stationing soldiers who shoot on sight, they manage the conflict by exchanging liquor.
