“A single bomber could take out that entire battle group.” So what? A single Chicom MIRV could kill 30 million US citizens living on the West Coast. Do you really want to go trading battle groups for states?
Can I pick the state(s)?
So, it’s not a threat.
I agree. A moving foxhole attracts the eye and surface naval vessels are the new dinosaurs. In a real war the carnage on the first day would make Pearl Harbor seem like a picnic. It is the one fact of life that makes China hesitant to attack Taiwan. (Aside from the fact that Taiwan just might have nuclear weapons.)
