That has been the recommendation for civil protection for a while already. Not so much because of the risks of war, but e. g. floodings, power outages, storms etc. And most importantly you should stockpile water, because at a power outage, there will be no tap water anymore. That's the most important bit people here seem to forget. So nothing new here, actually.
