I have actually posted that article from zerohedge before here https://steemit.com/news/@mf-tzo/german-government-urges-citizens-to-stockpile-food-water-in-case-of-attack-or-catastrophe
Since your post has more traffic I will repeat it here...I think everyone should first invest in long durable food and clean water for at least 3 months and then everything else. Fiat, gold, silver,stocks won't have much value when the financial world as we know it collapses.
