Israel has been attacked by Iran most of the last 60 years. True, Iran does it via terrorist organizations that it funds, but nonetheless Isarel has been under attack by them.
The propaganda machine funded by petro dollars in the ME has created this idiocy that people like you then espouse as fact. When you make statements that Israel wants to "wipe Iran off the map" and then are unable to back that up with anything to prove it, you act the pawn perpetuating the lie.
Israel in maintaining an aggressive posture against a nation whose leaders have stated, and quite publically so, that they want to annihilate Israel, (wipe them off the map) should be expected!
If you can't back up a claim, then don't make it.
