He did what a hokage was supposed to do...protect the village and endure.
Well so did Danzo but what he did doesn't mean he should be Hokage over other choices.
Sasuke referred to Itachi's actions as an official Konoha ninja, not as a undercover member in Akatsuki.
Well considering Sasuke is a missing ninja turned S rank criminal, I doubt he could make any decisions of what the Hokage and council would deem official ninja especially when they don't even know about it since only Kakashi, Naruto, and Yamato knew and Itachi asked Naruto to keep it that way.
Honestly, had he just tried to convince his father against the rebellion, he'd have done a lot for Konoha.
He said he tried but we don't know how and how hard he tried too. He would have to had pulled a Naruto haha.
Regarding 1,2 and 4: Itachi had Kakashi's life in his hand those times but he chooses not to kill him because his just pretending to be the bad guy. in fact, If he wanted to, he could have just killed Kakashi that time... Regarding their attempt to kidnap Naruto, perhaps it was just an excuse to visit Konoha and fuel Sasuke's hatred.
regarding #3: He knows Sasuke is smart enough and his array of electric-type attacks is an advantage against Deidara's.
Itachi told Kisame to kill Kakashi in part 1 lol sure he was risking 1 life fore thousands but he still did that no matter what. Itachi and Kisame went after Naruto again and was going to let Kisame capture Naruto by cutting off his legs. He had to do these things to be able to protect Konoha but Obito knew Itachi was dying from the disease so at most it was prolonging Obito's attack. Itachi didn't know Sasuke was going to meet Deidara and he actually thought Sasuke died when Nagato told him so; Kisame asked him if he was crying out in the rain.
He did more for the village then other kages. (Hiruzen, Minato [indirectly caused kyubi attack]) Saved the village by doing what a certain hokage was scared to do, then endured the pain of killing his clan and abandoning someone he loved.
Still cant see an uchiha as a hokage though. Being on the verge f extinction and everything.
Itachi did more than Hiruzen who fought in the first war, was Hokage during the second and third wars (gave orders that helped them win battles), and ensured peace in the village in his 50 or so years as Hokage with certain mistakes here and there. Minato fought in the third war and won many battles there which saved many of his comrades life. He also gave Naruto what he needed to become the hero that he did and sealed some of his chakra and Kushina's chakra in Naruto to ensure they can help Naruto at different points in his life. He prevented the Cloud village from getting the 9 tails that was in Kushina when he was a kid, pass down his teachings to his students such as Kakashi who helped the future of the village, protected Konoha from Obito and Kirama as well as giving his life to ensure Konoha didn't fall short in the power balance and condemn his son a life without at least one of his parents to give him power to use to fight Obito.
You left out that Obito was playing on taking out the Uchihas and probably would have himself since no one in that clan is beating his Kamui and Sasuke said only a few had the Sharingan at those times.
He spied on Akatsuki, relayed Intel about Akatsuki to Konoha.
Indirectly told Konoha what Akatsuki wanted during his invasion
He prevented a civil war within Konoha, even though he could have said no.
Jiraiya gave info to Konoha about Akatsuki, he's been spying on them since Orochimaru joined them which is years before Itachi was even born. We don't even know if the coup would have happened, Obito was planning on killing the Uchihas, Itachi found this out and asked to join and from there they made the deal that Itachi will join Akatsuki if "Madara" don't attack Konoha. So Obito would have still attacked the Uchihas even if Itachi didn't join in. Sure Itachi could have warned the Uchihas but warning them that Madara is still alive and want them dead would freak them out and they'll ask Hiruzen for help which would be a way to reunite them.
He stopped Obito from going after Konoha too. :|
He didn't stop Obito, he prolonged it, Obito knew Itachi was dying from the disease remember? And he still sent Hidan and Kakuza after Naruto and they were heading to Konoha. Obito wanted the 9 tails but since the Bijuus have to be sealed in order, he can easily wait until he had the others so he wasn't in a rush plus it took time just to seal 1 Bijuu.
The man saved his village from a coup by his own family...
True but if he didn't then Obito would have still went after them since Itachi discovered "Madara" planning on attacking Uchihas and had him join him. Sasuke said he didn't think Itachi could kill all of the Uchihas but we know Obito could have with his Kamui already allowing him to easily kill Jounins (Mist village Anbu) and that was before being trained by Madara. He can literally phase in a house, kill people and move on to the next target while they slept.
Plus when you put Uchihas vs a 7 years younger Hiruzen, Danzo (who easily beat Shusui who was an elite Uchiha like Itachi), both Anbu groups of Hiruzen and Danzo, Hyuuga clan, Nara clan, Ino clan, Choji clan, Shino clan, Sarutobi clan, Kibs clan, the other Jounins and Chunins then it doesn't look like Konoha would have that much trouble especially when Sasuke said only a select few had Sharingans (said this in part 1 so related to Uchihas in the time they were alive).
He stopped the Uchiha coup. lol
If he wouldn't have done that, Konoha would have been destroyed and the other nations would have took over it.
But Obito was planning to kill the Uchihas so wouldn't Obito had stopped the coup if Itachi didn't want too? It was Obito and Itachi that did it but Obito's Kamui plus training from Madara and Hashirama DNA puts him above any Uchiha at that time. How would Konga have been destroyed? Uchihas vs a 7 year younger Hiruzen+his Anbu, Danzo (who took down an elite Uchiha which is what Itachi was as well)+his Anbu root, Hyuuga clan, Nara clan, Ino clan, Choji clan, Shino clan, Kiba clan, Sarutobi clan, and the many Jounins and Chunins? You do know only a select few Uchihas had the Sharingan right? Sasuje stated that in part 1 so it was pertaining the Uchihas at the time they lived. Danzo himself said Hiruzen and his forces would had been enough.
OT. Itachi had a Hokage wisdom more after he died because what he did to Sasuke isn't what a sane person should do. He created a larger problem for the war because of that, Itachi understood what he did wrong after his death so at that time he would have been a good Hokage and even pushed Naruto in the right way when he was close to drifting off it.
