Iran
[Our Arab allies] would say [regarding U.S.-Iranian negotiations], "What is wrong with you people? You have this good, loving, loyal wife in us, and this crazy mistress in Iran. You don’t understand how bad she is for you, and yet you endlessly run off to her the moment that she winks at you."
The big winner in the aftermath of a Trump victory is Iran’s Supreme Leader... He will have the most cartoonish American enemy, he will exult in the (hopefully brief) crash of the American economy, and he will be able to walk away from Iran’s obligations under the JCPOA while pinning the responsibility on Washington.
