There is wide spectrum of potential ICBM strikes coming against you. It could be one ICBM, a few ICBM to a full blown first strike with 100s of ICBMS. It could be 1 ICBM exploding with nuke in an empty field (just as a warning). It could be a warning shot on a military target, again as a warning.
Are you going to do a full retaliatory strike with mass ICBMs of your own for all of these scenarios?
No, you are going to wait, assess the situation, think about all the geopolitical implications and then take action. Your own action could be proportional or disproportional depending on your goals. A full blown retaliatory strike is like suicide bombing, so your probably not going to that unless you are already sure that you are dead anyway.
Anyways, as I said before, this is my opinion based on my current understanding of world politics, and ofcourse China's own nuclear policy. We can agree to disagree.
