It's the Russian doctrine

Keep the population of hostile countries uneasy at all times, destabilise a bit here and there, help them argue about stupid identity politics instead of focusing on things that actually matter.

When people become complacent about Russians poking around here and there, breaking in and not doing anything etc - then when they actually need to act, the defence will be lukewarm.
