After how the past decades have unfolded, this just does not hit anymore as a realistic threat.
I do not care about Iran.
We have more important things at home to focus on.
Focusing on Iran is a distraction, at best; an outright detriment to fixing far more fundamental problems domestically at worst.
If Israel believes that Iran becoming a nuclear power is such a fundamental threat to their own existence, then fine. Let them do something about it.
Leave America out of it.
Well sure, because nuclear weapons stop working when idiots stop believing in them.
