What makes you think that Iran isn't a threat? You seem to assume that Iran doesn't have some sort of interest in the destruction of Israel/the West. Hasn't Iran's leadership said enough about their intentions?
1. They has no interest in the destruction of Israel/the West.
2. They can't destroy Israel/the West.
3. They have no intentions of destroying Israel/the West.
More to the point, why would they want to fire missiles at Israel when they're so incredibly outmatched by their nuclear arsenal? As crazy as a lot of the mullahs are they're not suicidal.
