I have relatives in Ukraine near bombing sites and I am hosting Ukrainians in Budapest right now so I am not taking this lightly. I just don’t like "armchair panic engineers" arguments like yours that is as vague and generic and useless as it can be,
I am not concerned about when WWIII will begin, I am very much concerned about when it will end. But don’t worry, you cozy middle-class life will not be more disturbed by it than a few extra bucks at the gas station. Oh, and the tubes! yes!
