Well, i think we should wait for Kishi to release the next chapter before we make any 'Naruto is an idiot' judgments. After all, this argument is basically overanalyzing what? three panels in this chapter, thats not really a lot of information to use. I would wait to see Kakashi or the other Ninja's reaction to Naruto's rash attack before saying 'he's an idiot.'

I'm going with DB on this one. Rash, but not without reason, he is after all, trained by the great Jiraiya, he had to have improved.
