Interesting discussion on what to do with Iran. Authors can't let go of their TDS, but its still an interesting perspective.

They think the US should warn Saudi Arabia (!).
Tell the Saudis we won't get involved unless directly attack.
Tell the Iranians we aren't doing anything now because we are mature but we have red lines (very Obamaish).
Let the Europeans work around sanctions.
Reinstate the nuclear deal.

"...For generations past, policymakers have often agonized over the possibility that actions they are poised to take will provoke exactly the behavior they are seeking to deter. Under conditions of uncertainty and where outcomes are consequential, the agony is understandable, even admirable. But in this case, hawks who believe a U.S. military strike on Iran will deter rather than provoke further Iranian military attacks and ensure the free flow of oil from the Persian Gulf are deluding themselves, members of Congress, the American public, and our allies in Europe and Asia. If there is a way out of the current crisis, we will have to talk our way out of it, and not depend on cruise missiles to convey the talking points."

Authors make some good points. But their judgement is clouded by hatred of President Donald Trump, hatred of Saudi Arabia and an ignorance of what Iran represents. It looks like more of the failed policies of the Obama administration.
On the other hand, there don't appear to be a lot of good options. I agree with them that regime change is not happening. But we can keep the pressure up like we successfully did with Ghaddaffi.
