NATO has forward deployed forces to assure that to take Riga, Tallin, and Vilnius, Russia will have to attack and defeat armed forces of the UK, Canada, and Germany respectively. More than that, really, those are just the lead nations in the NATO forward-deployed battlegroups in those countries. There are also five other forward-deployed battlegroups, four of which — as well as reinforcement of the original four in the Baltics + Poland – were deployed in response to the 2022 Russian escalation in Ukraine.
Cutting undersea cables is not going to prevent (or even meaningfully slow) a response given that.
