Israel is not "afraid" of Iran, neither is America, and it's more complicated than that. Both recognize the dangers of a nuclear armed nation under the control of the Mad Mullahs. It is not against Iran, and neither Americans nor Israelis have anything against the people of Iran. The three nations were allies before the crazies took over Iran. Fear would be if America and Israel were too paralyzed to act. We've seen Israel dominate the skies over Iran and chase them from Lebanon and Syria. You can expect some action to prevent a nuclear armed nuthouse.
