> If you consider an underwater cable running from Finland to Germany or Sweden

Well, if you only think about direct links, then yes. But run 5 cables up and down the coasts of Sweden<>Finland, then also for Sweden<>Germany, Denmark<>Sweden and Denmark<>Germany and you start having a lot of redundancy.

Of course, that also adds a lot of ongoing costs for infrastructure, monitoring and maintenance, so not a silver bullet exactly.
