AbdicationLast week I wrote that, as a political matter, Trump’s best option on Iran is to simply walk away:What Trump should do is walk away. Some readers responded by saying that Trump can’t, because Iran won’t let him. Nick Catoggio wrote an interesting column about how walking away from Iran would be, for Trump, like declaring bankruptcy. But Catoggio concluded that it’s not possible:[T]he president would happily choose the bankruptcy option, I’m sure, if only the Iranians would offer it to him. Today I want to interrogate whether or not Trump could abdicate America’s position in Iran.
