“The average US lifespan is brought down notably by inner-city/minority drug use and crime that Jewish life isn’t affected much by”
We are affected by it to some extent. Also, the suicide rate is probably much higher in the US, which unfortunately is also true of the Jewish population there.
My real point is that there are so many factors affecting a person’s lifespan, so you can’t really say that Israel is dangerous because of a few terrorist attacks. Even within Israel, terrorist attacks do not come close to being the main source of death. Car accidents are much more common, but no one considers it dangerous to live in Israel because of that. And no one avoids crossing the street or taking a taxi because of it.
Statistically speaking, the chances of being killed in a terrorist attack or even of being killed in a car accident are negligible.
