It’s ridiculous to posit that the US might take direct (or even indirect) military action against the fat little kid with the bad haircut.
That’s China’s job. And if Trump and his administration are doing their jobs, they are diplomatically encouraging China to take that action.
It’s more in their best interests anyways.
No, it is ours. Nuke em NOW. MacArthur told Truman the damn truth just like Patton told FDR and IKE.
