The important conclusion here is that Russia tried to influence the Baltic States by political destabilization (they had plans for Russia as a second official language, reducing importance of NATO) and it failed.

Russia seemed to have more success in Ukraine but ultimately they also failed when Ukraine appeared moving towards the West. That's why Russia ultimately decided to start a military operation, i.e., a war.

Of course, you could think that Russia would never dare to start a war with a NATO countries. Definitely the risk is lower. But we didn't believe it would start a war in Ukraine either. It is possible that any country can experience some kind of political destabilization (even without meddling by Russia) and they Russia could use the opportunity. So, it is important to be ready.
