Do you think there will be a third world war?

There is never going to be another big conflict like that, people are too educated and information is too easily accessible, leaders will not be able to convince people to go and die by the millions for their own interests. Besides, in the past wars used to actually be profitable, now diplomacy will get you more power and money than war ever could. War will continue to exist in small and uncivilized countries, or when the occasional tyrant raises in some god forsaken country and goes nuts, but something big like a world war? No, even a first world country going to war with another first world country? Will not happene ever again in human history.
