Here is Fred Reed, explaining why humans have always been and will always be irremediably, stupidly and suicidally vicious. And now that we have the hydrogen bomb the question is not whether we will use it. The question is when.
Another thing that makes human behavior hopelessly awful is the dog-pack instinct. We have an insuperable tendency to form packs and bark at other packs. In the case of some species, such as ours, a powerful territoriality is also in play. The urge to merge into a pack and fight with others is perhaps stronger than the sex drive. It is not unique to humans — ants do it, for example — but it is unusual in nature. Intelligent species, such as horses, form herds but don’t fight each other. So do whales. Cats don’t bother at all.
Countries (very large packs) fight and growl at each other, and form larger packs — NATO, the Warsaw Pact — to fight and growl at each other. These are immensely territorial. Members of these fanged herds do not actually pee on the borders to mark them, but come close…
Countries behave as idiotically as dogs because they are ruled by people as idiotic as dogs. Male dogs in a pack want to be alpha-dog, and fight to get there. Male politicians, to include the marginally female, want to be alpha-pol and fight, scratch, claw, lie, cheat, and steal to get there. Politics rewards the unprincipled and truculent, and thus those most likely to start wars. A fairly small number of these pathologically combative people decide whether a country of three hundred million go to war with another that most of the population has never heard of.
Misfortune can follow when people with instincts suited perhaps to small bands living in the wild decide on war for nations of hundreds of millions with nuclear arms. Their hormonal urges are exactly those encountered in bar fights. The pack follows them because, again, we are pack animals. It is what we do.
