More to the point than “watch logistics”, watch for large movements of troops within their own borders, and large fleet movements.
They’ll need work sorting out the log train and that’s done with large scale exercises.
Now, keep in mind I don’t watch careful so they might have already begun the process.
There will come a time when China will turn on us, and bite off the hand that feeds them. It will come quick. When it does, they will not be alone—they will have a peck of allies who wish to hitch their fate to the red Dragon. Few will be on “our side” in this conflict—we will see who our real friends are at that day. First will come the economic attack, watch our dollar plunge. Then the cyber attack, then the assassinations of key leaders in the media and politics (Rush, Hanity, Cruz, Levin etc...) Then will come the push, for us to withdraw from Asia. The next attack will be from space—with demonstartions on our telecommunications network. Only after this will they start to sink ships and bomb bases, Then threaten our cities. Will we fight back or fold up? I beleieve this world war is one we will lose—and along with it Hawaii and Alaska, Guam, and Samoa. I hope I am wrong!
