On the contrary, China should maintain or further emphasize no first use, so the full potential of China's generational or even multi generational advantage in accuracy and range can be realized.
A single DF26 by virtue of its accuracy when it comes to hunting an aircraft carrier can do what would take multiple tactical nukes to saturate the area. All that while having 0 risk of causing an escalation to MAD.
When developed further, fractional orbital bombardment HGVs should be able to reach comparable levels of accuracy. Nuclear use will not even be needed to deter the American invader at home, instead US landmarks can be bombed with pinpoint accuracy and complete impunity, because the warheads used will not be nuclear and China is widely known to disavow nuclear use.
However I agree that China should reach out and put its defenses as far out as possible - build fortresses - such as the one already built around the straits to defend the coastline and Taiwan should US try something.
If US continues to cut relations or even signs war acts against China on Taiwan, China should meet its long neglected old friend Cuba again, and perhaps a new friend, Venezuela. Building a permanent PLA presence with DF26s in these 2 nations will remind America that whatever their next plan is, the world is watching. So be careful.
