The difference between now and before is significant. Yes paranoia and lack of strategic intelligence meant there was the real percieved possability of attack against the Soviets.
Nobody even remotely believes the west would attack Russia or China first, never going to happen in the foreseable future. Everyone at the top knows that. The Russian people don't though, and that makes them ripe for propaganda.
The best thing Sweden and Finland could do is sign up to NATO and place the reasons directly at Russia's doorstep.
