That's why you divert what was going to the West into your own MIC and start pumping out weapons at the rate my grandmother makes dumplings. The US cannot fight a high intensity peer conflict when their stockpiles of munitions are depleted by their misadventures in Yemen, Israel and Iran. They won't be able to sustain replenishment either because they don't have the raw inputs courtesy of China cutting off rare earth exports.Too aggressive a restriction would trigger military action, with the historical oil embargo on Japan triggering conflict with the US being a big example, so it was something that had to be modulated in any event. What matters more now is military preparedness, of which the PLA is much closer now to fully actualizing given recent developments.
