I am afraid that this fear of Russia is blown a bit over-proportion and is used by the US to gain even more dominance of the World military power. Russia was not really successful in it's invasion of Ukraine and Ukraine is a lot smaller and closer to Russia then Sweden. Not to mention the geographiclly harder to conquer. At this pace I dont see that Russia can invade Sweden in the next century or more. While joining NATO right now will indirectly mean that Sweden increases it's military and particapates in NATO involvement in the middle east. It is a bit scary how centralized the power balance of the world has become. US is now involved with almost all wars in the World and is invading coutries like Iraq, Syria, Libya without any justification and no repricussions, just for oil. I am more scared of the US and I think that is reasonable.
