I think Nagato's idea of peace by giving power is not that crazy. For example, in real life, nations like the USA and Russia had a Cold War but no one fire the first shot because both side knew that a nuclear war will destroy both sides. Unlike the war between USA and Iraq, Iraq didn't have nuclear power and the USA didn't see a real threat and so USA started the war. But if Iraq had nuclear bomb in the first place I don't think the USA would have risk a real nuclear war. Because Iraq was a small nation with out the ultimate power(or nuclear bomb) USA didn't care and pawned them. USA didn't dare to touch Korea and Iran because they have the ultimate power.
So, Nagato's idea is to give every nation the ultimate power to prevent war. But his idea is a little strange because he said that war will happen and peace will follow. I'm a little confuse on his idea because even without him there will always be war and peace. I think someone messed up the translation from the raw.
Not quite, we're not at peace at all, even the small seemingly-peaceful times are covered with agony, pain, death, and turmoil. Nagato's idea would never work, in the end, it would just destroy everything...leaving nothing and no-one alive.
Looks like Naruto's been shaken quite a bit, but hopefully...he ends up telling Nagato that he's got the concept of "Peace" wrong, and he'll destroy Yahiko Pein by unleashing the Kyuubi (or something related..any power boost)...I'm sure Naruto would stick to his guns, stating his Nindo and how he will never stray from it, hell, he might even add bringing true peace to the world to it.
One thing's certain tho, Naruto will kill off Pein in order for Madara to achieve his goal...how else is Sasuke going to come back into play, only other way is for Pein to escape with his life and have the cycle of Pein all over again, new 6 Realms, same strategy...and of course things might change, but Naruto would be prepared, and the Leaf Shinobi know Pein's secret, so he won't be much of a threat in the manga anymore...he will have finally become a minor villain.
End of Pein and his goals...Madara Uchiha's time to shine (even though I hate the motherf***...)...none of you can deny that he will be the final villain...at the moment, too much info is spread out about Pein, he's become weak and liable to being Killed Off.
Madara is still the Invincible Immortal(even tho Itachi stated he was "a shell of his former self")...Madara can't even be touched due to his extremely advanced Space/Time Jutsu.
