On the 37th Day they will detonate the bomb over Tel Avive. It will be a dirty bomb too. Second bomb over Haffa. The USA will have to move the people to the USA. BUT Israel will counter attack—and there will be no large cities left in Iran. Israel will be no more.
I hope you are wrong. But I believe, like you, that the Persians will make multiple attacks at once. The Iranians want more than one bomb where they will attack and then threaten attack with their other nukes.
