Iran never said they'd nuke Israel; they didn't even say they'd wage a direct war on them. They said Israel wouldn't be around in 25 years. A LOT of people are getting sick of Israel's ultra right wing nonsense. They are surrounded by a lot of potential jihadists who they piss off regularly, they annoy a lot of their own citizens as well as a lot of their formerly staunch supporters. They will die of right wing rot (sort of like us) way before Iran needs to nuke them.
