@The Archangel: Tajuu Kage Buunshin no Jutsu was sealed by the First Hokage and there have definitely been wars since then.

What I would really like to know where the "you get your chakra back when a clone dispells" idea comes from, has there been any actual evidence that this or is it pure speculation to try and avoid the idea that Naruto has been shown to survive, and even continue fighting with only:
(Naruto's # of base chakra units - 1000 * the cost of a shadow clone)/1000 units of chakra.

It boggles my mind too, but I don't remember anything that implied that he was getting chakra back after blowing it on clones that did nothing.
