I wouldn't exactly call them ninjas anymore. They kind of lost that title when they started flying, breathing in space, and creating New York cities in what is supposed to be called the "Hidden Leaf."
That reminds me, why do call all the villages "Hidden" when they have like road signs and such to tell you when they are located and if people know where they are?
That is given.
I mean, remember when childrens around 12 y.o. fought to death on a simple C (or D?) rank mission? Or remember when orphans was recruited as spies, or trained between themself in battles to death. Or when group of 12 y.o. was sent to deal with a group of criminals that was trained under a veteran of previous world war? (Great idea).
Guess risking lifes of childrens is okay, and 8 walking nuclear weapons is not even question to consider.
"Gonna surpass all previous generations" to only enforce everything that was done before.
Not talking about sending spies to kill leaders of other smaller countiry leaders, that is given for a better future of the world.
