Your retort is shallow, and bears the same observation I made previously about your comprehension of history. However, now what needs to be added is that you do not understand how decisions like that are made in armed conflict.

De facto, if your statement was true, nuclear weapons would have been utilized in every major conflict since then, by a nuclear-armed power, and that has happened ZERO times, although, unfortunately, there have been plenty of major conflicts in which it may have been utilized as an option.
