“but technically, the odds of a person being harmed in a terrorism attack in Israel are lower than the odds of being harmed in a car accident there, and the odds of being harmed in a car accident there are very similar to the odds of the same thing happening here.”
While it may not be significant, if both America and Israel have similar rates of harm via car accidents and Israel additionally has terrorism then Israel would be less safe. Now obviously the preceding sentence doesn’t take into account other possible harms which might be more prevalent in America. Also, it is possible that the existence of rocket attacks actually minimizes the amount of car-related accidents because people are afraid to drive when a rocket might land at any moment.
