I don't think the people who control Iran are logical rational people. I think they are religious fanatics who firmly believe that Allah will protect them and/or give them 72 virgins. If they don't nuke Israel themselves, I think you will find them slipping some bombs to Hezbollah and Hamas and letting them do the dirty work. Since it doesn't look like Netanyahu nor Obama is going to take out their nuclear facilities militarily, time will tell whose assessment of the Iranian leadership is correct. If Israel does get nuked, I hope I am there at the time. I couldn't bear to live in a world without the Jewish state.
