You, good Sir, pretty much summed up my own feelings on the subject; attacking Sweden would feel like a joke, at least in a modern setting.
I already play some Grand Strategy, where areas need conquering and rebellious Swedes get put down and their cities given to my heirs. So technically I've killed plenty of my own countries military, though only in a historic setting so far. Which was when Sweden was actually a big military power in Europe, some 200 years ago, and people had cause to declare war on us.
Nowadays we don't have much of a standing army, or reason to maintain any large enough force to fend of invasion. So, as with Ireland, it'd be a really short game. You'd conquer Stockholm in a blitz attack, probably in under an hour, and we'd surrender before too much got broken. Then we'd try to talk our way out of the conflict.
We have IIRC 40 000 people (That includes the home guard) to defend a total population of about 9,5 million. Our military chief of staff a couple years back (Not sure if he retired or not since) estimated that our ability to resist a serious invasion from a well organized attacker would only be able to hold out for at most 3 weeks. And yeah, we can pretty much forget about any coastal city, when we can't even keep Russian subs from floating straight on to the capital and can't keep Russian jets from flying over our territory. Hell, I don't even know if out coastal defence gun batteries have been updated since the 60s. I doubt it.
Only way for us to not be obliterated instantly is most likely to withdraw up North to the mountains, but then I'd assume the inability to supply necessary resources (Like food) would be what would ruins us. You can manufacture and stockpile all the munitions in the world (We do produce a crapton of munitions - Which we sell to non-democracies - Hypocrisy woo!), you still can't fight on an empty stomach.
So yeah... Not a lot of confidence in out defensive capabilities, because even the guy in charge of it all lacks confidence in them.
