Someone in PLA commander center is quietly counting US troop's missile interceptor inventory and calculation how long it take them to restock them.
US crashed Iraq, spent $2 trillion. Then Chinese contractors got most or Iraq's oil fields contracts. US troops defeated Afghanistan, spent 20 years and another $2 trillion and then got chased out of the country. No China has more influence there.
If US is happy to play the world cop with its own money, PLA must be happy to be the bystander to watch the US show, hopefully for the next 50 years.
