'Yielded some positive results- and none of that happened' . Mr. Feldstein is contradicting himself. It will not be in the interest of the USA if the President, or anybody else from the administration, antagonizes others around the world for the purpose of antagonizing and, possibly, just entertaining hillbillies. It will not be in the interest of the USA if the President calls Iran the principal source of islamistic terrorism, while the entire world knows, that Saudi Arabia has been the hotbed of it and continues to be. There would not be an ISIS without Saudi Arabia. The President's world-view is dangerous and will not 'yield some positive results'.
