Obama is careening madly toward the cliff. He wants to assure the destruction of Israel and the US before his term is up. No one seems able to stop him so Saudi Arabia and the Gulf Arab States to go nuclear as soon as possible to counter the Persian threat, Egypt as well. That will be Obama’s legacy.
Iran has enough nuclear material, based on estimates, ten bombs. Limiting the number of centrifuges slows things down but doesn’t stop development.
And Saudi Arabia has already paid for nukes from Pakistan, just waiting delivery the moment Iran says it has nukes.
That rivalry is already bad, from driving the Iran-Iraq war of the 1980s to fighting in Pakistan today, with the occasional killing of Almaddhi and Christians throw in on a given Friday.
Sunni-Shia fighting + add nukes = nuclear war
