China is one of the world leaders in AESA radar and they have basically cloned the S-400 missile system by this point. Chinese ships would have better defensive capabilities against such weapons than US ships. That's what I don't get. Why is it the US always assume the other side won't strike back? Eventually they will suffer from this aggressive posture.
Huh? The DoD, the war college and bunch of other entities s are constantly running war simulations, reevaluating opfor using the latest intel they have on China, Russia etc. forces.
Do not confused the average American civilian and certainly politicians on matters of war and war fighting.
There are many extremely smart and highly capable analysts and strategic thinkers in the Pentagon and other places.
I can guarantee you those folks definitely would not be assuming that countries like China won't strike back. If anything they would likely overestimate Chinese capabilities not to dissimilar to the 1980s when the Pentagon almost w/o fail almost always overestimated Russian capabilities from unit level to training, preparedness and strategies.
The same with Gulf War I, II etc. Why do you think we won the war so easily? Because we significantly overestimated Saddam's warfighting capabilities and planned it as such.
