WHERE'S OBAMA ON TRASHED IRAN NUCLEAR DEAL ?

What's President Obama's opinion of his signature foreign policy achievement being trashed by Trump? Obama made a realistic deal with the Iranians on nuclear issues and economic issues. The terms made sense. Trump and the neocons come into power and renege.So now we stand teetering on another catastrophic war in the Middle East.And Obama? What does he have to say?The silence speaks volumes.Could it be he won't give his opinion unless paid? Could it be Obama was more a billboard notice for identity politics rather than a capable trustworthy executive?
