"The Norwegian information also talks about how to survive for three days without power"
The prepping recommendation for Norway has been increased to a week.
That's also true in the US. FEMA says to prep for a week now.[1] Used to be 72 hours. In recent large-scale floods, which are now happening in areas that did not used to have them, areas have been cut off for a week.
Here's the Swedish pamphlet mentioned in the article: https://rib.msb.se/filer/pdf/30874.pdf

I mean canned food etc is useful but you wouldn't even die from starvation if you stood outside for that amount of time.
What we really need to become as prepared as we once was is mandatory conscription. It used to cover almost all men, today I think it covers 7-8 percent of those in the right age. Without having seen the defense from the inside, it must feel foreign and abstract. But it concerns us all and should not be something for a just a few.
The ongoing Ukraine war is what prevents these countries from being invaded now. Winning that war by destroying Russia’s ability to produce conventional weapons, and exhausting its supply of military age men, will protect these countries and NATO for at least a decade. Which is time Europe needs to prepare.
