u seem to be forgetting all the shinobi who fought the sound/sand nins, and the 3rd hokage who managed to stop oro. naruto's achievement was small compared to teh village as a whole.

plus, naruto wasnt' the only one who stopped gaara. u have to consider everyhitng sasuke did before naruto got involved. and also, nartuo didn't beat the racoon monster (shukaku?), gamabunta did. all naruto did was punch gaara a few times.

it wasn't any individual effort that won the war, so u can't say that so and so was all powerful before.
