The chance you would die in a terror attack is almost nonexistent compared to the chance of dying in a car crash, falling off a cliff or just randomly stabbed by some fuckhead.
So who cares? If you always think about all the ways things could go wrong you'll never be able to even leave the house.
Being afraid means letting the terrorists win, and I live in Israel, I know what I'm saying
Europe and Slovenia in particular are pretty fucking safe (except for those narrow winding roads in the mountains, seriously guys drive slower)
