Should European countries position military craft at 1km intervals on the surface along the route of every cable? Or do you mean they should start cutting Russian cables?
But when they want to escalate, any convenient pretext they can fabricate will be spewed out
Appeasement ONLY encourages aggressors. They can ignore any statements and rhetoric and correctly conclude: "I did X, no real consequences, therefore I can do more X".
The ONLY language they understand is force or consequences with real cost to them. Vladimir Lenin said it very clearly:
>>"We probe with bayonets. Where we find steel we withdraw, where we find mush we press on."
When delaying reciprocal action, the cost for the next round ALWAYS increases.
Delaying response is a fools' game.
Democracies always play that fools' game because for any one politician, it is easier to kick the can down the road with bad reasoning like you posted.
But when the situation finally becomes unavoidable, it is a deep serious problem. Here we are.
Hmm. Although I've never read that tome, it would not surprise me to find he expresses similar strategies.
It's really just the Imperialist Autocrats' standard playbook, and it is little different from the schoolyard bully — "What's mine is mine, and what's yours is up for grabs".
They all just keep aggressing until they get hurt, then they find someone else to harass and steal from.
If that's actually the framework, then you need to respond not reciprocally or in kind or 'tit for tat', but to overwhelm. Speed, surprise, and violence (literal or metaphorical) of action.
Lack of reciprocal action is called self deterrence. Or in simpler words, it's what happens when you keep doing what the bully at school asks you to do, more and more, because he could escalate, even if you are as strong as him or stronger.
No, there is a VAST menu of effective retaliation or response measures. The response absolutely does NOT need to be exactly in kind or 1:1.
The key is that the measure must cost the aggressor more than they gain, and of course be reasonably proportional.
Plus, even if we stick to your irrelevant requirement, response is better. It is less bad to have no subsea cabling for everyone vs making no response and ending up with only the aggressors having subsea cabling.
That's one possibility, but another is that they're deterred. Suddenly doing the bad thing hurts, so there's a good chance you'll go find some other person to pick on.
But of course you can't /know/ the outcome beforehand, which is what makes it a high-stakes game. The only thing you know is that if you keep doing nothing they'll have no reason to stop.
Ban, arrest or damage "shadow fleet" tankers that transport Russian oil. Control their supply chain e.g. stop selling them spare parts for stolen planes. There are many things, all the way to taking hostages, but EU needs to grow some spine to do that.
Non-credible: Cover the coasts with Anti-Submarine Torpedo Rockets, and the moment you detect an issue in your submarine cables / pipelines, launch at the position :D
Even more non-credible: Use the nuclear-armed version with a small nuclear warhead
Because it is not the entire crew of those vessels which are complicit in these actions. It is far more likely that one person dropped the anchor - which does not seem to register on the bridge, no warning lights seem to be installed if I can trust what I've read and seen on this subject - so it would bounce over the bottom. The autopilot will take care of keeping the vessel at its programmed course and speed until the anchor gets stuck (which seems to have happened the last time a cable was cut somewhere off Gotland, the vessel suddenly went from 6 kts to 0 kts and staid around that speed for about 30 minutes).
That does not mean such vessels should be let off. They should be held at anchor until the responsible person(s) have been identified and the vessel's owners should be held financially responsible for the damages. Once a few owners have been made to pay up they'll make sure it becomes impossible for an individual to go out to the bow at night to drop an anchor without anyone noticing.
