Of all the countries Russia fears, Sweden is _way_ towards the bottom of the list. Source: have a brain, am a Russian.
The Russians aren’t concerned that Sweden are going to invade them anytime soon; they are concerned that, should the Russians get a bit carried away in their geopolitics-by-force games, the Swedes may be a heck of a nuisance.
Yes, the weapons exist, but suggesting that they could just be casually employed without massive global repercussions is absurd.
Besides, if things were getting hot, the Swedes (or anyone!) would be fools to keep their naval assets in port; doubly so when those assets are largely autonomous and easily hidden, like submarines.
The Norwegian navy also operates a few diesel-electric subs; in cold war days, the plan was to let the Soviet surface fleet enter the fjords, then give them hell - the point being that just about any Norwegian population center or strategic asset is - drumroll - by a fjord.
Hence an invading navy would have to venture into the fjords to support the land forces - the fjords packing subs, coastal artillery, torpedo batteries and lots of observation posts to make the stay interesting.
Noone thought the Norwegian armed forces could repel a determined aggressor - the idea was to keep the foe busy (bleeding profusely in the process) until NATO allies could arrive.
The other Nordic countries probably had similar strategies.
Russia is more scared than you think, since their capital literally became in firing range in a short period.
The enemy is not an army, but internal unrest.
Have a country next door with a bunch of subs you can’t detect is a threat. Remember these “puny conventional” submarines are the ones that ran circles around an entire US carrier taskforce, the crown jewels of the US navy. I doubt Russia has anything significantly better.
Like the rest of the Soviet military assets, it suffered heavily in the collapse of the USSR, but there hasn't been the revitalization effort in Putin's administration that there has been in the Army and Air Force.
The rest of the fleet is comprised of Kilos, Akulas, and Oscars. These would have been formidable in the 1980s, but they're outclassed by most NATO fleets (excluding Germany which has let their entire military collapse).
Your sub-launched ASMs are nice though. Wouldn't want to be on the receiving end, but since most of the SSGNs don't leave port, not really much of a threat.
So, just these four nations have combined economic power to match Russia: Russia can't afford a sustained war, though it may afford a quick act of aggression (a la Crimea) followed by everyone pointing fingers at everyone else. But it's a risky game because it will push their economy even further behind.
Headline criticisms are unsubstantive to begin with, but it's particularly unsubstantive to make up a different headline and criticize that instead.
Besides which, as mentioned ITT, when one reads TFA, the only mention of Russia is as a threat to Sweden: "simulating attacks", "infiltrating territorial waters", etc. There is no support in the text for any Russian fear of anything. Let us not go so far overboard in defending sensationalist headline-writing editors.
