Go back and study the history of First Sino-Japanese War and you will understand why I believe this.
You're going to need to be far more specific than that.
That war took place 50 years before Hiroshima and was a disaster for China that led to further problems and the eventual collapse of the country's government.
They achieved none of their war aims and were weakened and humiliated.
In a post-Hiroshima age, why would China be motivated to emulate an abject failure from their past?
