Regarding the May 10 editorial “Iran’s ‘moderates’ and the Holocaust”:

I thank The Post’s editorial board and Robin Wright of the New Yorker for highlighting this travesty and questioning the motives of a “moderate” Iran. Besides providing further evidence to regret the Obama administration’s Iran nuclear deal, the pieces highlighted that country’s duplicity and the naivete of President Obama and his advisers, Ben Rhodes among them.

What is going on in Iran is no different from what happened in the United States last year: An influential faction, disdainful of the sitting president and his policies, contrived its own Machiavellian move to appease its base and score a point, as did then-House Speaker John A. Boehner (R-Ohio) and his likeminded group in inviting Israeli Prime Minister Benjamin Netanyahu to address a joint meeting of Congress. This was done behind the back of the executive branch and in blatant defiance of the country’s foreign policy establishment to derail the Obama administration’s nuclear negotiations with Iran.  

Iranian Foreign Minister Mohammad Javad Zarif could be just like Secretary of State John F. Kerry, who was kept in the dark by Ron Dermer, Israel’s ambassador to the United States. During a lengthy meeting, Mr. Dermer didn’t say anything to Mr. Kerry about Mr. Boehner’s invitation.

We should give the benefit of the doubt to Mr. Zarif and take him not only, as the editorial suggested, “at his word” but also in his deeds; just like Mr. Kerry, he may not have been a player in this circus.
