I agree wholeheartedly. Ever since Jiraiya's death, Naruto has seen it as a personal goal to add to his others to fulfill Jiraiya's goal of ending all ninja war, and the fight with Peine has really drilled that home for Naruto. It only further solidifies the fact that the original Team Seven are following the exact course that their Sannin predecessors took many years in the past, though each for different reasons.
Also if you remember, Jiraiys was offered the position of Hokage before Tsunade was officially asked to be one, with him ultimately turning down the elder's offer.
I think Naruto (the manga) is going to end with Naruto (the ninja) pulling a Lelouch ending from Code Geass R2, with how Lelouch brought the ENTIRE world's hatred upon himself and them killing himself to bring true peace to the world. I think that because look how Naruto reacted to ninja team when they wanted information on Sasuke a few chapters back.
In truth, I don't believe that either Naruto or Sakura are close to being qualified for being Hokage, nor do I believe that they ever will become one. Both are far too heavily influenced by their emotions, which Ninja in their world are supposed to be stripped of; if anyone should be Hokage from their age group, I'd say either Sai or Shikamaru are the top choices, but even they are flawed and not yet worthy of that title.
