Why do people have children when there is always a risk of war?

I don't understand why you would expose someone to that risk. Like my mom who was terrified during the Cold War that war would break out between NATO and the Warsaw Pact but then still decided to have me. Maybe it was optimism because the Cold War was over but she should still have been aware of things like the Yugoslav Wars and Rwandan Genocide, meaning war isn't gone because it will never be gone.

I often get told the chance is small so I shouldn't worry about it. But I assume Ukrainians and Lebanese might have thought the same a few years ago. I just don't understand how you can do that to someone.
