To the people who voted for Naruto's world:
Many of you are still living in this fantasy Naruto Universe. It's about time to get out of your box and get some fresh air into your brain. Don't get me wrong: I love Naruto as much as all ya'll, with the overpowered characters, various jutsus, crazy weapons, amazing story, etc. However, you seem to be mixing this fantasy with the little reality you have left. Logically, the Naruto universe cannot win against the real world. Yeah, the Naruto universe may have tailed-beast bombs, Kekkei-Genkais, summonings, etc but it's nothing compared to the modern military arsenel; lightning fast rockets, tanks, submarines, jets, automatic rifles, nukes, etc.
And if the difference of weapons does not win you over, think about the number of people on each side. Take the Naruto-side; a united country that probably has about a few hundred thousand shinobi at most. Not so shabby. Now let's weigh the real world; a united force of various nations that possess a garrison of at least a several million soldiers altogether. Unless your sense is out of wack, you obviously know which side will prevail.
The only way the Naruto-verse has a chance is if the Five-Nations decide to allow "Tobi" to carry out his "Moon's Eye Plan" and hypo-toad everyone. However, I don't think they would let the fate of two worlds rest on a single, power-crazed and vengeful man like Tobi; whoever the hell he is.
For many of you, the borderline of fantasy and reality are very slim. You need to pull yourself out of that Genjutsu before it's too late. Yeah, Naruto's Nindo way is to "never give up". However, you should look what happened to Japan at the end of WWII.
