It will appear futuristic: The Global Government, The Global Congress and the Global Army-UNITED STATES OF THE WORLD. But until then the nations of the World torn apart by their interests such as security and distribution of food, water and other vital resources, will continue to do what they did as long as our ancestors were mammals and even before-fight, fight and fight.
I, personally, believe in the goodness of a human kind to realize sometime that it's own survival is in humanity own hands.
Otherwise the old trick might work for a while -the appearance of a common enemy, like an alien planet. That will unite everyone living together and stop the wars for a short time.
