Pure political theater with a badly written script.
Anyone who actually believes that this agreement is going to reduce the odds of an attack on Iran is ignoring the reality of Israel and Saudi Arabia. Both cultures are terrified of Iran but as an economic rival rather than a military threat. The Sunni-Shia schism is just a cover used by the corporate media to conceal the truth about the strife in the region.

The other secret no one wants to talk about is the actual alliance between Israel and the Saudis/Sunnis and the simple fact that most of the funding for Al Qaeda and ISIL comes from the Saudis and the Gulf States.
All the people in the US who have been persecuted for donating to "front groups" suffer while the real funders are our "pals".
