Iran's leadership has also previously promised to wipe Israel off the face of the planet using nukes.

I don't give a crap if they don't have one yet... Israel should've proactively eliminated them a long time ago. The rationale of waiting on destabilizing state to have nukes before acting is absurd. Had this been handled long ago a lot of people in the ME would be alive today. Iran does not just seek to wipe Israel out, it's minority islamic branch is the cause of many/most conflicts in the ME (some in Africa) and has undermined peace between semitic peoples.
