when did the war start in naruto shippuden
Naruto With Nagato's eventual death, Tobi, disguised as Madara Uchiha (one of Konoha's founding fathers), announces that he wants to get all nine Tailed Beasts to perform an illusion powerful enough to control all humanity, to create world peace. The leaders of the five ninja villages refuse to help him and instead join forces to confront Tobi and his allies. That decision results in a fourth great ninja war between the combined armies of the Five Great Countries (known as the Allied Shinobi Forces) and Akatsuki's forces of zombie-like ninjas. The Five Kage tries to keep Naruto, unaware of the war, in a secret island turtle near Kumogakure (Hidden Cloud Village), but Naruto finds out and escapes from the island with Killer Bee, the host of the Eight-Tails, and the two of them head for the battlefield.
Pacific War The Pacific War saw the Allies pitted against Japan, the latter briefly aided by Thailand and to a much lesser extent by the Axis allied Germany and Italy. The war culminated in the atomic bombings of Hiroshima and Nagasaki, and other large aerial bomb attacks by the Allies, accompanied by the Soviet declaration of war and invasion of Manchuria on 9 August 1945, resulting in the Japanese announcement of intent to surrender on 15 August 1945. The formal surrender of Japan ceremony took place aboard the battleship USS Missouri in Tokyo Bay on 2 September 1945. Japan's Shinto Emperor was forced to relinquish much of his authority and his divine status through the Shinto Directive in order to pave the way for extensive cultural and political reforms.[42]
