@Jermofoot:
That or Zhuge Liang. Actually, I’d choose Zhuge because he knew of what Sun taught (and used it on Sun’s descendants) and applied it to everything else he knew.
That’s interesting: some people say that Zhuge Liang’s campaigns on Wei weakened too much Shu and leaded to Shu’s fall. Maybe if Shu saved more force and focused in defense they could hold more against Wei. On the other hand, I think both Sima Yi and Sun Quan handled better their resources (after all, Wu was the last of 3 kingdoms to fall and only fallen to Jin - Sima Yi’s descendants)
I find that similar to Justinian’s dream of recovering Roman Empire: it only wasted Bizantium’s resources to a lost cause, and let they in bad shape to fight against the real threat: Persians and, later, muslims
