Yi Peng 3 crossed both cables C-Lion 1 and BSC at times matching when they broke

October 2023 there was similar incident where Chinese cargo ship cut Balticonnector cable and EE-S1 cable. Chip named 'Newnew Polar Bear' under Chinese flag and Chinese company Hainan Xin Xin Yang Shipping Co, Ltd. (aka Torgmoll) with CEO named Yelena V. Maksimova, drags anchor in the seabed cutting cables. Chinese investigation claims storm was the reason, but there was no storm, just normal windy autumn weather. The ship just lowered one anchor and dragged it with engines running long time across the seabed until the anchor broke.

These things happen sometimes, ship anchors sometimes damage cables, but not this often and without serious problems in the ship. Russians are attempting plausible deniability.

What are some concrete reasons why someone would want to damage these cables? Who benefits?

Russia wants to end NATO without going to war with NATO.

NATO's political unity and ability to respond is tested with these attacks. Russia does them one after another gradually escalating. Russia maintains plausible deniability or does so small operations that they can always walk them back.

Eventually, some country invokes Article 4 or 5 consultations. Russia hopes that US, Hungary, or Germany waters down NATO response. The conflict continues, but between individual countries not under NATO. NATOs as a organization may continue, but raison d'être is gone.

Russia and these NATO countries being probed are like the two siblings in the back seat. Mom, he's touching me. Stop touching your brother. Mom, he's holding his finger right next to me. Dad eventually says, don't make me pull this car over and start a global thermonuclear war

Not quite. Be careful, Russia invests a lot in disinformation campaigns and spreading (conflicting, but that is part of their doctrine) narratives. Bothsidisms and False Equivalency are some of the common tools in muddying the information sphere.

NATO and Europe did quite a lot to normalize relations with Russia. Russia was invited and became participant of the NATO program Partnership For Peace [0].

   The program contains 6 areas of cooperation, which aims to build relationships with partners through military-to-military cooperation on training, exercises, disaster planning and response, science and environmental issues, professionalization, policy planning, and relations with civilian government

Very nice, but the secret services that took over the empire did and does not fancy a rule-based, harmonious order based on mutual relations, human rights, freedom of press etc. As any autocracy or kleptocracy understands, that is very much a threat to their power, beacuse

  - Population will demand political influence.
  
  - Mindset. A criminal thinks in terms of I win, you lose. Might makes right. Complete opposite of what makes up the dna of the free world. 

The imperative is on us to understand that message really well. It goes slowly unfortunately. It is hard for us to grok.

Notice how on our part, helped via tech oligarchs, there is an incessant bombardment to undermine support for those values. Kremlin troll factories are a thing, but the Chinese are speading up rapidly in the information sphere too. Especially youngsters are targeted.

The war has already begun, but we don´t want to see it. And that is dangerous.

These anti disinformation posts are quite peculiar. I'd advise anyone who wants to dig deeper to listen to West Point graduate Mearsheimer:

It takes one hour to listen. Take notes and verify the facts afterwards. No disinformation there, much less Russian.

Mearsheimer, who bases his theory on 'Putin never lies'. Sorry if that's your starting point then you're just promoting fantasy.
