That guy needs to have his eyes checked, because I don't see it:
Relations between the U.S. and Iran have warmed since the agreement, to the dismay of U.S. allies like Israel and Saudi Arabia. The once hostile foes are cooperating to end Syria's civil war. [emphasis added]
Our relations haven't warmed--as increased Iranian threats to our forces in the Gulf show. No, it's just that we've backed down in the face of Iran's actions in order to preserve the farcical nuclear deal.
The idea that America and Iran are cooperating to "end" Syria's civil war is a complete distortion of the trend of America increasingly working to support Iran's objective of propping up the Assad regime in Syria by defeating the multi-faction rebellion.
And even this guy admits that in as soon as 7 years, Iran's nuclear weapons path threat domestically re-emerges. Yay Smart Diplomacy!
But while the writer says that the threat of war would return if Iran takes that path, I suspect that by the time that occurs, Iran will have purchased a nuclear deterrent from North Korea. With so much of the West focused on Iranian territory to spot nuclear facilities, why have we assumed the Iranians are too stupid to adapt to that focus?
