If I we're Chinese and wanted to attack U.S. Besides the obvious conventional invasion techniques, I would use all of my loyal Chink students, faculty, business reps, doctors at all of the U.S. colleges, Universities, businesses, etc. They would serve as an already infiltrated guerilla force. I would then attack soft targets with these armed Chinks to control key infrastructure, think logistics, airports, sustenance (water food), transportation. I would also attack Schools that tend to cage children in with only one entry and exit. This would force the parents and the communities to comply and not uprise against them. The Chinks would say "Just turn in your weapons here and we will give your children back to you." I would try to control Walmart distribution centers or super markets in order to control food supplies. I would advise your audience to be vigilant in the next month or so.
