Zarif Says Deal Heralds 'New Chapter of Hope' (for what?)

Iranian Foreign Minister Javid Zarif said Tuesday, "Today could have been the end of hope but now we are starting a new chapter of hope."

Zarif said:

I believe this is an historic moment. We are reaching an agreement that is not perfect for anybody but is what we could accomplish. Today could have been the end of hope, but now we are starting a new chapter of hope.

For the hope of Iran to be able to obtain a nuclear weapon and threatened Israel and the entire Middle East?
