Re: The Leaf VS All 4 Other Villages
Once the konoha ninja spread Minato's Kunai around the battlefield, he literally solos all of the enemy fodder ninja.
Even if he runs low on chakra, Kurama can presumably give him more; so all he has to do is teleport to Naruto, get some chakra, then go back to raping the fodder.
While Minato destroys the fodder (With occasional chakra from Kurama) you got people like Hashirama, Madara, Hiruzen, Itachi, Jiraiya, Orochimaru, Tsunade, Tobirama, Kakashi, Gai, Sasuke, Danzo, Naruto, Ino-Shika-Cho, K11... the list goes on. You got all of these guys to handle the top ninja from the other villages, and the average ninja from the other villages as well.
Some of the greatest thinkers and strategists are in Konoha. The Nara clan, Kakashi, Itachi, Minato etc. Konoha has so many advantages, it isn't even funny.
Tsunade can summon Katsuya and have her multiply to heal the wounded simultaneously. Jiraiya, Naruto, and Minato can summon an army of toads from Mount Myoboku. You got three Susanoo on the battlefield (Sasuke, Itachi, Madara); and one of these is a Perfect Susanoo, which could destroy an entire village with ease.
Naruto's KCM shadow clones rape.
You got two people (Three if you include Kabuto) that are capable of using Edo Tensei. You got the Senju clan, Hashirama's wood release, and Yamato's weaker wood release. If you include the Uzumaki clan as part of Konoha (this is questionable) then you got the best seals to ever exist in the Narutoverse also in Konoha's favor.
You got a couple of fastest ninja in the manga from Konoha.
We just haven't seen enough from the other villages for them to even compete with the versatility of the Konoha ninja; alive and dead. I probably haven't even listed everything Konoha has to offer, and they still take this with little difficulty.
