Right, as I mentioned important stuff is encrypted before it hits the cable. However, my point was that by encrypting submarine cables we introduce a whiff of steganography into the play. Cables using encrypted data streams sans source/destination/IP addresses info make neutral territory - the ocean bottom - redundant for third parties to snoop. When forced onto land their presence is more likely to be detected and after cable station fanouts/distribution points the common tap points no longer exist thus greatly complicating their spying efforts.
