It would take about 55-60,000 missiles to even strike every building in Shanghai. That's about 55-60 years of US missile production. Just to take out a single factory, about 20-30 missiles are required. And China has hundreds of thousands of factories. A single missile hitting a factory is not even enough to delay production for 8 hours.
During WW2, the allies dropped millions of tons of munitions on Germany per month, yet Germany industrial output grew every single year. Chinese industry today is 20-30 times larger than Germany industry of WW2, modern industry is about 10-20 times more resilient than WW2 era industry, and Chinese ability to rebuild using modern technology is 10-15 times more than what the Germans had available to WW2. And the US today cannot even deliver ordnance at 5% the rate at which the Allies delivered over German cities in WW2. Do some basic research before posting brain dead claims.
