How To Put An End To Wars

Doesn't it strike you as odd that, as children, we all spend an awful lot of time studying wars at school? Why would any sensible mind think that it is a good thing to teach children about wars? Some might argue that the History of humanity is important and has to be passed on. Some others might say that studying wars might prevent more wars to come. To the latter, I would respond that they are obviously wrong. I would even go as far as to say that I don't see why that aspect of History should overshadow other aspects such as laughter and humor. Wouldn't it be better to teach our children how to make beautifully articulated jokes than to surreptitiously plant in their minds the idea that going to war is, sometimes, a necessity?

Wouldn't we live in a better world if world leaders were to play jokes on one another instead of bombing ordinary citizens?

If there are other intelligent beings in our universe, I wonder if they're affected by the same plagues than we are. If they're not, I'm sure they would admire a lot more our species for its ability to laugh than for its self-destructive tendencies.
