It's not insane, but it would be a horrible and bloody hot war, the likes of which we haven't seen since WWII, and it would probably eclipse WWII in total deaths. But it's not "insane", because we have precedent for it: it's exactly what happened in WWII: the world's largest economies and industrial powers going into an all-out war, culminating in nuclear attack, and resulting in the deaths of tens of millions. It's…
Uh, no.
The US overt, initial war aim would be an existential threat to the Chinese regime, and China is a nuclear power with intercontinental delivery capability. It would see multiple times more total casualties than WWII, and that's just be on the first day that China was convinced that the US was serious about the effort.
