Because once a country gets plugged in by one cable, they realize that it's not enough. If they're going to build an industry around it, they need to know that their connection isn't tenuous but permanent, because if a cable breaks, you have to send a ship out into the water, throw a grappling hook over the side, pick it up, find the other end, and then fuse the two ends back together and then dump it over.
Jo, kad valsts tikusi pie viena kabeļa, viņi saprot, ka ar to nav gana. Ja viņi grib ap to veidot kādu nozari, ir jābūt pārliecībai, ka savienojums nav šāds tāds, bet gan pastāvīgs. Ja kabelis sabojājas, kuģim jābrauc jūrā jāmet pāri bortam satvērējs, jāatrod kabeļa abi gali, tie atkal jāsavieno un jāiemet atpakaļ ūdenī.
