Can food last 100 years?

Yes, certain foods can last 100 years or more if preserved properly, with honey, dried grains, and well-sealed canned goods being prime examples, though quality (taste, texture) may decline significantly, with honey being the most stable and some canned items showing no microbial growth even after a century. Key factors are keeping items dry, free from pests, sealed (especially cans/jars), and avoiding temperature extremes to ensure safety, but always inspect for damage (dents, rust, bulging) before consuming.

What country would survive World War III?

No country is truly "safe" from a major global conflict like World War 3, but some nations are considered less vulnerable due to geographic isolation, political neutrality, or strong defenses, with New Zealand, Switzerland, Iceland, Bhutan, Australia, Chile, and Ireland often cited as potential havens because they are far from major power centers and generally non-aligned. These places benefit from distance, stable governments, ample resources, or robust civil defense, but all would likely suffer from global fallout like economic collapse or nuclear winter.

For long-term survival with just two foods, a combination like potatoes and milk (or yogurt) comes close, providing carbs, protein, and some vitamins (milk needs vitamin C), while sweet potatoes and eggs offer excellent vitamins (A, C) plus protein and fats, but no single two-food combo is perfect; a varied diet is always best. Other strong pairs include beans & rice, or a trail mix of nuts, seeds, and dried fruit, though these still lack some essential nutrients for indefinite survival without supplements, notes Valley Food Storage, Reddit, Battlbox.com.
