The 'your' was generic. Terrorism is a rounding error in accident, injury, and death statistics. It does not make us materially less safe. It does not change the fact that Belgium, Germany, France and the UK are some of the safest countries on Earth to live in.
If you want to make that argument then 9/11 was just a rounding error of the 2.4 million deaths in the USA in 2001.
What is your definition of safe? Do you have a percentage figure of terrorism related deaths where it becomes 'unsafe'?
