As far as I know, nothing about Iran's foreign policy decisions in the last 43 years shows that Iran's government makes foreign policy decisions in a less pragmatic way than the average country. If Iran got nukes, they would almost certainly just use them for deterrence purposes like all other countries have since 1945. Even if they didn't, though, I have no desire to definitely go kill Iranians now just to prevent some hypothetical future deaths of Israelis. If it was up to me I would cut off all US support of Israel tomorrow and let them figure out their own issues. If you personally want to go fight against Iran, there is nothing stopping you. I would rather not get dragged in to it, though, and I would not want my tax money as a US tax payer to go to murdering Iranians for the sake of soothing your bloodlust and/or your fears.
