I hate that these things happen.
Memories are short, it emerged in around 1990 in an admission by Andreotti (Imo ultra sleazy) who was Italian Prime minister at the time
That there were "parallel structures" within the European states, which had been involved in terrorism since the mid 1960s. In Italy, they were known as "Gladio",
They had been responsible for probably all "left wing terrorism" including the Milan and Bologna railway station bombings and the kidnap and murder of former Italian prime minister Aldo Moro.
Similar parallel structures were present in the other Countries to the west of the wall. This was openly admitted in the Early nineteen nineties (see the three part BBC time watch documentary about gladio, on YouTube).
Similar stuff emerged in Russia, when secret service people were caught planting explosives to blow up apartment blocks, to be blamed on Chechens.
the story was published by Alexander Litvinienko. Who someone then assassinated by feeding him Polonium.
An attack on a shopping street in Stockholm makes absolutely no sense as an act of war. None at all. It's not likely to affect any of the key people or structures of the state, or the people and Plants involved in weapons production.
It only makes sense as part of creating a "strategy of tension" of setting people at each other's throats, and looking to rulers for protection.
A "strategy of tension" is probably best summed up by a quote from H L Mencken from around 1920:
The art of practical politics consists of keeping the population afraid, and hence clamourous to be lead to safety. This is achieved by menacing them with an endless string of hobgoblins, all of them imaginary
