The US has too many idiot lawyers as politicians. The thing about "nuke buttons" is that they can only be used once and that's it, in addition to the global economic disruption that will inevitably hurt world trade and mainly US companies because they also market their products and services in China and they want to get their deposits in US banks, in dollars, there is the problem that China is the second economy in terms of nominal GDP and the first in terms of GDP PPP, it will create a great incentive to create an alternative system as soon as possible. It will be inevitable, even US vassals cannot escape the fact that they have great economic connections with China.
