What are the risks? That people die. Do you know how many people died of preventable things just today?
Or it's scary because it means we're going to go to war? Then why aren't we scared sooner? Be scared of the thing that causes people to want to blow up planes. It's not like they just wake up one day and a country decides it's going to blow up a plane. Our government spies off so many people and the result is we're still scared to get on planes? What a waste of money
I encourage you to look in to how risk is calculated. There are several ways, and all of them - excepting layman's attempts and Claude Haiku responses - are on a spectrum, not a binary. They do not resemble what you have provided.
