China is the greater threat in that their economic future is in front of them and Russia’s is mostly behind them IMO. As we lose our economic strength to China, the world will begin to accept their strength more and more. As they do, one day, the pendulum of world confidence will change and the US will no longer be able to just print money and when that happens…life as “we” know it will change drastically.
Russia is the greatest threat. China isn’t much of a threat, as long as they are making money and have investments in this country. That’s my main worry about a trade war with them–they can eliminate us as a trading partner, and then we don’t have as much leverage, and they will be more of a danger to us.
