I have not looked at a map. My guess is that most of these cables are linear - point-to-point.
Obviously a more robust architecture is a ring. All TransAtlantic cables are rings, but can you justify the economic cost of a ring architecture to serve relatively small countries? Hmm ... Despite the needless worrying about terrorism, the single most important factor is how well a cable is buried. Deeper is better and more expensive. To bury a cable, you dig a deep trench, drop the cable in it, and let Nature cover it. Nature is very good at doing so ... Roderick S.
