Israel: bonafide nuclear power
Iran: would-be nuclear power
Israel: never threatened to use any such power to eliminate Iran
Iran: constantly threatens directly and indirectly to eliminate Israel
Israel: surrounded by over a dozen nations within reach of nuclear fallout
Iran: would evidently not care about dropping that fallout all over those predominantly Muslim nations, Arab, Persian, and Turkic alike
Israel: has thousands of Palestinian citizens living and working there
Iran: would evidently like to incinerate those Palestinians as much as the Jews
Israel: has solid documentary evidence of Iran backing terrorist actions responsible for the death of their citizens
Iran: has solid documentary history of proudly backing terrorist actions responsible for the deaths of Israeli citizens
To you in charge in Iran, I hope you enjoy the hell you're going to bring down on yourselves. When that bomb slaughters Palestinian Muslims, Palestinian Christians, Druse and others, when the fallout lands in Egypt, Jordan, Iraq, Syria, and Saudi Arabia, what do you think your Muslim brothers will do to you to avenge their dead?
To you the Iranian people... it was nice knowing you. Too bad your leaders are looking to get the entire eastern hemisphere of the Earth to turn on you.
Oh wait, did I forget the inevitable involvement of Russia and China and that your country will be center aisle, front row seat for that aftermath?
Sucks to be you.
