> why now?
Probably to inflict pain on the life of the voters so they can blame the government and manipulate the 2027 French presidential election in April. Maybe just a test.
Same as the high velocity train being sabotaged again just in the Spain national day. Hybrid war.
Come election day, do you really think many people's deciding factor would be a supermarket refrigerator incident from half a year ago? Especially considering that around the same time something far more... shall I say politically meaningful was happening at the same time, such as students protesting the lack of school funding?
