This thread is purely based on historical version of 3 Kingdoms, and not the novel part.
After liu bei passed away in 222AD, he handed shu kingdom to his son liu shan and also zhuge liang and Li Yan. But Zhuge liang still holds most power and authority.
during his tenure, he advocated military confrontation against wei for at least 5 major times. And all his military expedition was failures.
Was Zhuge liang correct in embarking on offensive military campaigns against a much strong opponents? Or could he have just employed a more inward growing and adopted a wait and see kinda approach? Would that have resulted in Shu lasting longer or grew stronger in the long run?
