Never surrender to China in the battle of language, Washington. Ceding control of the words we use can be fatal to diplomacy. If you let someone define the words used in an argument how he pleases, or if you let him use terms so imprecisely that they lose all meaning, you let him establish the assumptions from which the argument proceeds. And once he sets the assumptions, he can prove whatever he wants. You will lose every time. Call it rhetorical battlespace preparation, or call it “three warfares.” Whatever the name, it’s a never-ending campaign for Beijing. Blunting it demands similar persistence.
