You know. I get that this is a boring dystopia. But it makes sense for an economic magazine (one that has been around since the first two world wars) to talk about the economic aspects of a looming world war.
It even acknowledges in the article (more than once) that financial concerns are far down the priority list in such a case. But that as a financial publication, this is their purview so they're focusing there.
There's a bit in the article in the direction of "war introduces such radical levels of uncertainty that even past occurrences provide few lessons to learn from". (Can't get a direct quote.. returned to article to be stopped by paywall) It goes on to say that this uncertainty is heightened because any future world war will involve nuclear powers.
I hope that knowledge of the level of uncertainty is enough to deter the spread of violence. But that hope may be as futile as hoping people would actually read the article
