Yes! I have not been there myself but I have family members who went. Israelis suffer from terrorist attacks but they live their lives normally. It’s like in US when we hear the “threat level” has been raised. We don’t stop going on with our lives. So yes it is safe. If you are really concerned you can go with a tourist group, they often have extra protection when you go around (armed soldiers etc.) to make everyone feel secure.
All my life I’ve been waiting for “One Day” when there will be peace in the entire world and we won’t have to worry anymore.
