Israel will never be able to gain acceptance in its location by bombing others in the neighborhood.
Iran is at most, a verbal threat to Israel. Iran has 77 million people and no number of any sort of bombs will cause Iran to leave, to cease to exist, or to become Israel's buddies.
Israel is one of the least popular countries on the planet. Bombing Iran will make them even MORE unpopular. Many Liberal American Jews, and there are a lot of them, will stop sending money, stop investing money, cease to donate money to Israel.
This has already begun to happen with the Israeli government subsidizing the unproductive Ultra-Orthodox who pay no taxes, have dozens of children, refuse to serve in the military and live in subsidized housing. Their only activity is Torah study. When they retire, the Israeli government pays them a nice pension. On the Sabbath, they come out and throw stones at people who dare to drive a car and yell at girls wearing tanktops and shorts.
They are pretty close to the fictional Welfare Queens that Reagan spoke about. With the important difference that they exist.
