It is difficult to imagine Israel attacking Iran.
It is, however, more difficult to imagine Israel not attacking Iran.
Consider three questions:
First, does Iran mean what it says about destroying Israel? When its leaders repeatedly call for Israel's annihilation, after referring to it as a cancer and using other rhetoric not heard on a national level since the Nazi regime's depiction of Jews, is this just rhetorical flourish? Or do they really hope and plan to destroy Israel?
Second, can Iran do it? One can hope and even plan to do something outrageous, but that does not necessarily mean that one can accomplish it. So, the second question is whether Iran can destroy Israel, or at least murder a high enough percentage of its population and destroy enough of its infrastructure to enable surrounding Arab states to invade and do the rest of the job that the majority of Arabs favor (even if some of their governments have a peace treaty with Israel).
It seems to me that the answers to the first two questions are so obvious that any burden of proof rests on those who argue otherwise. Do they think Iranian leaders are bluffing? Why would these leaders bluff? And why would one think they are bluffing given their faith-based hatred of Israel? I write "faith-based" not to argue that Islam necessarily demands the destruction of the Jewish state, but because that is what the Iranian leaders believe Islam demands.
Iran is ruled by people who believe it is God's will to destroy the Jewish state. It is also a country rapidly acquiring the ability to use nuclear weapons to achieve this goal – through direct attack, handing nuclear weapons to terrorists or both.
