There are no parts of Sweden that have majority Russians living there, and there are no Russian military bases here, so we would probably be safe.
Our land connection to Russia is also not as crucial as Ukraines.
No Swedish province would have a referendum to join Russia, so it couldn't ever happen in the same way as the Ukraine conflict.
We are two vastly different countries and cultures.
Also, there wasn't much talk about having to join NATO due to "Russian aggression" before the reckless events in Ukraine, which $5 billion spent on promoting "democratic values" in Ukraine helped facilitate in 2014.
However, if we had an agreement with Russia of letting them have a military base on Gotland, and our government was overthrown with a government that threatened to discontinue that, we would probably deserve to be invaded if we were unwilling to come to some kind of diplomatic compromise.
