How the world can avoid war today?

Honestly, to prevent a Third World War, I believe that we all should first learn to respect each other, because I think that if World War III ever occurs, it would be because of our current status regarding the dealing with racism, cultural issues and religion. A lot of people support this ideas but more than a thousand people are still living in the dark age. We are all the same, although our characteristics are different, our faces are different, our blood is still red. We should act mature now, since it is no time to act childish. All religions tell the same thing, but in a different way, and we should understand that. Another thing is that we should stop wasting money on useless expenses and providing money to illegal occupations and donate those money to countries that severely need it. We should also set our priorities straight, meaning, first comes country, then comes family then comes you. Many people have done great servings to this world, but this generation seems to care less about world issues which may occur in the future. We all should receive proper education if we want to make this world better, as education also plays a brilliant role in preventing the occurrence of a Third World War.
