Well since we can’t be invaded or subdued in a war (nor could China, Russia, India, or really any nuclear power) the amount we spend on “defense” is a bit extreme anyway. We could topple China by simply treating them the way we did the Soviet Union. No trade and minimal diplomatic ties. The starving rural hordes will take care of them for us after their economy collapses. Why 6-7 billion people kowtow to 1 billion Chinese peoples’ every whim is beyond ridiculous.
Actually, China is more like a billion three, but who’s counting. China is doing a fairly good job of collapsing its own economy. First a shutdown so severe there were literally people starving because they could not shop. Then throwing everything wide open with few cautions, and lots of sick and hospitalized people. The Chinese government and economics is also sending foreign business to other countries in Asia in substantial quantities.
