Who thinks that an army is unnecessary?

Narrow-minded. Even if we disregard national differences, there's the economy to consider. There are developed countries, and then there are, for example, Third World countries. What reason would the former have to unite with the latter?
To put it simply: when parents have money, it makes more sense for them to give a gift to their own children than to some random person on the street.

And of course, people have no reason to fight, and there haven't been any military conflicts in the last few decades. :smile01:
