Wow, are you a fan of 罗贯中 (三国演义)? did you ever read the history of 三国志? Let me explain to you point by point:
1) Yes, there is a split between people believing in 三国, is either fantasy or history, your's apparently fantasy.
With great respect and apologies, though I do not fit as an apologist for Zhuge Liang but sad to say much of your apparent claims that some are fantasy, well I do know some are ideals perpetuated by the author of the Romanticized version of the chronicles for Warring Era. But perhaps you would want to spot out specifically which is "fantasy" in your point of view and my error as a dumbbell.
2) In 三国志, there's only so called 4 Tigers, Guan Yu on the left, Zhang Fei on the right, Ma Chao in front, Huang Zhong at the back. Zhao Yun is widely used by Zhuge, not Liu Bei.
Well whether 4 or 5 is not the KEY issue at cost here, the key issue at cost here is the APPARENT unwavering loyalty of these "tigers" whether 4 or 5. I am of the opinion that if they 4/5 "tigers" certainly men of their times, pledged loyalty to Liu Bei, then I of "lower" birth hold their decision of high regards. And therefore in that sense, Liu Bei is to be held in high regards. In simpler layman term, if your grandfather, your great grandfather, "juo gong" "juo Ma", holds certain value in high regards, then with sufficient evidence, so is your consent to be paralleled to that of your ancestors.
3) I never say Ba Shu hated Liu Bei, i'm saying they never support Liu Bei, especially financially. Who would want to support a lord invading your own land? Shu was doomed to perish sooner or later, Zhuge managed to prolong it..
Whether you believe in the actual chronicles or the romanticized version, I think the best evidence to debunk your point of views would be the Chengdu yesterday, TODAY, and Tomorrow.
Zhuge Liang already envisioned the economic viability of Chengdu and it sits right smack in the heart of CHINA. In fact, Chengdu connects directly to all major cities in China as a centre. The Silk road cuts through Chengdu. It is the GATEWAY to the entire nation via the HEART of the country.
And just fyi, CHENGDU today is the 3rd City with largest Mobile phone owners, 2nd City with Largest private cars ownership. Its domestic consumption for one particular industry alone is MORE than SINGAPORE's GDP!!!! of =/1 SGD140BILLION.
After the big battle with Wu at Yiling battle, Shu was in a very bad state, immediately after Liu Bei's funeral, Zhuge ask for a truce with Wu. Lu Su, prime minister of Wu was invited to Shu to sign the peace treaty, when he was his way back to Wu, he saw the poverty state of Shu and tell Sun Quan :"This nation is doomed, Shu is not a threat to Wu anymore", Lu Su was right, Shu was the 1st nation to perish 1st.
Zhuge Liang was adamant to fulfill his Lord wishes to unite the whole China under Han dynasty again at almost all cost.
You should read the 出阵录/on Wu Hou Shi's wall, the passion, the love, the eloquence, the love for the country to fully grasp the tension at that time. This was a man truly moved by clear objectives in life.
SO, even if Zhuge become the emperor of Shu, he cannot save Shu from being perished. Why? there are hierarchy in Shu government.
1)
1st generation officials - Guan Yu, Zhang fei, Fa Zhen, Zhuge, Zhao Yun, Ma Chao, Guan Xin, Pang Tong etc etc
2)
2nd generation officials - Jiang Wei, Wei Yan, Li Yan, Ma Dai, Ma Liang (these generals were recruited during the forming of Shu.) (Wei Yan and Ma Liang were beheaded, Li Yan was demoted to commoner)
3)
3rd generation officials - the riches, the warlords, the origins in Ba Shu itself.
Of these 3 hierarchy, Zhuge can only trust the 1st generation officials, the other 2 are not 100% behind him, especially the 3rd generations, because they are the origins of Ba Shu, why should they listen to invaders? so they always vote against Zhuge decisions.
So Zhuge have to make every decisions by himself and enforce it. Zhuge died at 53 because he tires himself out, because he cannot trust anybody..
4) Xiao Qiao?????
5) errr... I didnt say Zhuge is half pass seven, i'm saying his reign as prime minister in Shu was his greatest achievement during that era. His lost to Sima Yi six times in a row showed that he wasnt a great strategist at all, thats a fact :p
Since you touched on a hypothetical assumption here, then I shall also hypothetically reply to your assumption that had Zhuge Liang had it his ways, Sima Yi would have long fall under Zhuge Liang. Sima Yi knew he was not Zhuge Liang equal. Even at his death, Zhuge Liang was able to hold off Sima Yi hot pursued.
The infamous last 7 military campaigns led by Zhuge Liang were plagued by courts politics which Sima Yi orchestrated indirectly to divert Zhuge Liang furies. Even Cao Cao foresaw the deviant-ness of Sima Yi and ordered his son never to use this general. If even Cao Cao could see that Sima Yi
心速不正, and if you held Cao Cao in high regards then you too should subscribe to Cao Cao's opinion of Sima Yi.
In the art of war, strategies or military maneuver counts for half of the battle. Zhuge Liang was not lacking in strategies against Sima Yi but the former outmaneuvered Zhuge Liang via politics not entire through military.
Zhuge Liang did tire himself out but I do not think that it was because of his mistrust but rather of his onus to bear the weight of the entire military campaign himself for fear that other generals could fail thus threatening the entire mission. I would suspect few were as tacit and fluid as he was in militarism. There were principles that he could explain to layman especially in areas like science and geography.
Like for example = did he really borrow the East Wind from the Gods or he just simply knew of the change in wind direction coming soon?
Actually Chinese harbors many great scientific knowledge even before so call "pendulum theorem" came into being. If you look closely at the Chinese almanac, weathers prediction were already incorporated in them and they are still precise even till TODAY. Chinese physicians depended on these forth-knowledge of weather to prescribe medicine according to the weather as humidity will affect certain prescribe medication.
Zhuge Liang in his advance knowledge of the forth coming weather knew the east wind will be blowing soon but scholars in Cao Cao's camp probably not as advance as Zhuge Liang stated otherwise hence giving Cao Cao false confidence that enemy would never use fire to attack his chained naval fleet. Zhuge Liang then could not just go around telling the generals or Zhou yu "according to my knowledge and studies -- ying yang. .bla bla bla - east wind will be blowing ...". He had to use methods believable then to convince them, which was pagan worship and pagan-styled prayers to ask for east wind from heaven.
Hence, in short, as much as I wished I am worthy being an apologist of Zhuge Liang, I think I am far from that and unworthy even to say I adores him dearly. But, you my worthy learned friend, are fixated on your point of views with glimpses of history and without considering the actual standing of CHENGDU today. Much like Parameswara did not capitalize on Temesek potential.
I am inclined to believe, Chengdu today stand as a living testament to Zhuge Liang's lifetime work.
Somehow, you gave me the impression that you belongs to the camp of people whom I would call the "darth vader" sympathizers. Those who somewhat saw the "good" in the evil while those who idolizes Luke Skywalkers are the weaker race refusing to see the inevitable collapse of the Empire.
In conclusion, I dare not go up "Liang" mountain without 三两三 but certainly my penny worth weights a little heavier than your pound wisdom as your rebuttal were narrowed at a few instances of what I call "hypothetical point of disagreement" while ignoring other major aspects of historical and most importantly CURRENT records for/against Zhuge Liang.
