For those that think China is about to attack Taiwan, you might make sure you have enough food and water, just in case. What might happen first is they attack the US, not nukes, but cyberwarfare. Take down our grid, communications, internet, hospitals, 911 call center, and other infrastructure-related entities like the water supply. There are thousands of Chinese in the US working on attacking us with our own technologies. There are thousands of outdated routers in use today that we already know that they have setup bots within their memory. The FBI recently was able to hit the kill switch on one such group who had several hundred router employing thousands of bot nodes that had a package waiting to be triggered. That was one group of scores of groups operating in the US. Like Bush said after 911 - they only need to get it right once, but we have to get it right 100% of the time.
