Chinas nuclear forces are not to be worried about too much on the U.S. mainland. Our Aegis destroyers and fighters would pick them up in time and
shoot them down.
Most of Chinas nuclear weapons are aimed at Russia as they are in hardened silos in the mountains near the Russian border with them. They do not trust
the Russians at all and they are not about to nuke their bread basket the U.S.
China worries only about our pesky aircraft carriers so they are developing advanced nuclear cruise missiles to counter the threat because they are
smart and know that building more than a few missiles to target the U.S. serves no purpose for them as they can never win that fight.
China is all about defense so they have nukes to do just that. To the last post, The U.S. would obliterate anyone who nuked any part of the U.S. Our
doctrine is one where we now have and always plan to have the ability to launch a first strike that will destroy Russia and China if thats what we
wanted to do.
