Considering the NordStreams and that they became a taboo topic in EU, a cut cable would mean a lot of finger-pointing and not much done.

When Shetland had two cuts the other month, disconnecting the entire island, I don't remember any finger pointing

Sometimes things like that are a demo of capabilities.

Countries like to demo their war capabilities to other nations simply as a kinda-threat.

Such demos help stop war happening, so I'm not against them. Wars only happen when two countries believe they will win a war. If one of those countries believes they will lose, they will just admit defeat before any actual fighting happens. If countries are aware of eachothers capabilities, there is less chance that both countries believe they will win.
