Denmark and Sweden. What is worse - to take responsibility of the Nord Stream pipelines crash or to be unable to find the terrorosts?

Sweden and Denmark face a difficult problem. They are the countries where the terrorist attack on the Nord Stream pipelines happened. The close proximity of the pipelines to the territories of Sweden and Denmark and the recent announcement by a NATO member that the Baltic Sea is the NATO sea makes them fully responsible for the security of the pipelines. Essentially, NATO is the only party who had full control over the region and all possibilities to hide the preparation for terrorist operations. In case this was not NATO or its individual member(s), who detonated the underwater bombs, it would be an indication that NATO sees nothing in front of its nose, does not have appropriate control over critical infrastructure, and is unable to provide adequate security to this and likely other infrastructure objects.
