I think if we had some type of war with China -- my investments would be the last thing I would worry about. With the state of our population I'd be afraid of runs on the grocery stores and banks. Give some of these boobs 3 days without meals and some areas of the country would look like a Mad Maxx movie.....

If you are active in any kind of prepping, there's always a future to look forwards to in your plans. It's those that cover all their basses that can & will reap the rewards. The world won't fall just because China takes a stand on it's goal of dominating the world.
Same could have been said when Germany or the Soviet Union were taking their chance at global dominance. In the end they failed. Who's to say that China will be the victor in this conflict?
As much as others believe it'll be a Mad Maxx environment, I still believe that in communities, people will still band together and face threats together.
If not, I planned for that contingency as well. Nothing like a good 'ol hunker down & pooing in your makeshift septic
