Two undersea cables in Baltic Sea disrupted

And also the cable between Lithuania and Sweden:

And also Ireland escorted a Russian spy ship away from their cables:

A disruption in communications can mean only one thing: invasion.

yes. What Russia does currently is probing and testing - what it takes to disrupt all the necessary cables simultaneously to create communication breakdown and a lot of chaos, what resources and time it takes to repair (and thus planning the options on blocking those repair resources, etc.) It takes tanks half-a-day to cross the Baltic states to reach the sea. That is the time Russia wants to buy. Once Russian forces are already in Riga, Tallinn, Vilnus, the NATO will have a decision to make on whether to bomb the Russian forces already placed by that time among the Baltic states population.

This would be more concerning if Russia had any tanks left.

Are you suggesting Russia has a full invasion force they’re not using in Ukraine? Or to liberate their own occupied territory?

Baltic states have 30K military total combined - Russia loses 20-30K/month in Ukraine. So, with all the respect to the Baltic states military - with them being responsible for the defense of about 700km long strip of land, it isn't about full invasion force, it is about having NATO not responding long enough.
