Earlier I wrote about the Iran “bind” and I’ve had a second thought about the options available to President Trump. Perhaps he needs to follow the FDR model. What’s that, you ask?
The way FDR got past public opinion against going to war was to keep piling economic sanctions on Japan until they attacked us at Pearl Harbor. This caused public opinion to become orders of magnitude more hawkish. A declaration of war was voted nearly unanimously with no delay.
Presumably the same strategy is available to Trump. He can keep making life hard for Iran, without war, until they snap and overtly kill Americans. Those deaths should cancel most of the anti-war sentiment at home.
