Well, that's just my opinion. Germany's infrastructure was attacked, Sweden said "We're not gonna share our findings with German intelligence". Not sure how there's any situation in which Germany should go to a literal war - no questions asked - should Sweden be attacked if Sweden cannot even share their findings when it comes to an attack on an supposed ally.
Would you be willing to help out your neighbor if he told you that he has information about who robbed your house but won't share it with you? I highly doubt it.
Sweden doesn't care about NS2, but they'd rather not embarass the US (if this is true). After all both countries were very vocal since day 1 that Russia blew up their own pipelines. I'd love to find out the truth, even 10 years from now.
