WWIII: Will It Happen?

I believe that there will not be a World War Three, for different reasons.
Firstly, countries are more sophisticated and informed and intelligent. They know that fighting is not a way to solve problems, and that there are better solutions to disagree with others. And even if there are people who don't think this, I think the majority does, so they will convince the others.

Also, there are many "peace" organizations, and many people have joined them, and there is even a peace day. School all over the world celebrate it, and are pro peace.
This is why I don't think there will be a world war III.
