I agree with LostAngel. A "true" leader is one who inspires. Hinata, Sakura and yes even Sasuke have expressed a desire to become stronger. All because they were "motivated" by Naruto's performance.

Secondly, please do not discount Naruto's intelligence and strategies. He actually has a good grip on his abilities, and is still progressing toward development. No-one, including the Hokages, started out as a master ninja. everyone has to grow and develop.
