America will 100% not do that, unless they want matching craters in all of their fabs, or worse, in Taiwan’s.
lol China wouldn't bother bombing anyone
they'd just tell all their export ships to turn around and stop all exports
US would collapse in 30 days
it would be like the blockade US is doing to Cuba except 90% of every product we use and they wouldn't have to fire a single shot
they could also sell off the billions in US bonds and other assets
US economy would be utterly destroyed, we'd never recover because even the middle-class would be living out of their cars (now dead because all the parts for them are made in China)
Of course Amurica will not do it themselves, Amurica will outsource the job to someone else.
