Queen,
1. No place is 100% safe. In America one cannot even go to a shopping mall or an office party without fear. Not to mention home invasions. The fact of the matter is that the intentional homicide rate in Israel is much lower than in the US – and much of it is “family honor” killings among Arabs. Americans, however, have come to accept their situation as normal. When the first Gulf war broke out the hevruta of a friend of mine received a frantic phone call from his mother. When she calmed down she said very matter-of-factly “BTW, last week your brother was held up at gunpoint”.
2. Ramban says (Sefer HaMitzvot – mitzvot that Rambam “forgot”) that there is a Tora obligation to live in EY in our time.
