Over 20 years ago the president of Iran talked about "the regime occupying jerusalem must dissappear from the pages of time".
IE they want regime change in Israel - which is exactly what the Israelis want in Iran.
The difference is Iran is a more responsible international actor and has not started two wars based on this pretext.
So yes, I trust a nuclear armed Iran much, much more than I trust a nuclear armed Israel.
You'd trust a country that funds terrorist organizations with nukes? Let's not put you in charge...
