This is not true. Submarine cable installations generally have a lifespan of 20-25 years although that's even being extended now to 30 years with advances in WDM gear. Also in water deeper than 1500 meters the cables are typically laid on the ocean floor. This is done because it is beyond the limit of trawl fishing anchors.
>"Interestingly, spying breaks always involve three simultaneous breaks in the cable. The cable is broken at two points, and then broken at a third point in the middle to put spy equipment."
Yeah this is not true at all. Where did you get this from? Fiber cables can be tapped by simply adding a bend radius to the cable which allows it to leak. [1], Further you can shoot a light down both ends of a fiber and easily discern that there is more than one break in the cable.
