> What are we doing? Is it necessary? Depends how you look at it. In the wild, humans evolved to be watchful and suspicious of threats to their tribes, mainly other tribes trying to take what's theirs. So they'd make weapons to defend themselves. Modern humans have huge tribes (countries) and the weapons they create are also huge (nuclear, armies, drones)... but the threat remains the same... other tribes they don't trust There's also natural selection at play here. Tribes which don't/can't defend themselves are taken over by those who can... it's a sad truth that won't be changing anytime soon
