both industrialists and military know that a war with China is unwinnable
well (if it stayed a conventional war ), at this stage , US much stronger and battle hardened than the Chinese so very winnable in fact BUT risky (nukes) and expensive
so very uinlikely and if it did happen I imagine very limited in locale (Taiwan) and scale If US pushed the envelope and positioned their fleet would be very difficult for China to defeat it China won't be joining war with the US inside the next 5 years , probably next decade but is strenthening every year .
