The argument separates an objective's theoretical value from the resources needed to hold it. A Japanese airfield on Guadalcanal could force Allied convoys to detour, but the Pacific crossing was already so long that the added distance offered limited strategic return. Japan nevertheless began building far from dependable support and without a garrison capable of protecting the site. An optional forward position became an expensive commitment once the Allies challenged it.
