Hi there,
Tourists in Israel feel perfectly safe eating in restaurants, using public transportation and shopping in the mall due to the heavy security presence.
Israel police is spread all around the center of the towns and Israeli police personal are well trained in preventing danger.
For what I can gather on the net, most people suggest that
Middle Eastern countries are on average safer than Western nations and as long as you use common sense whilst traveling and dress modestly all should be fine.
Hope this helps
