Trump should have been satisfied with demolishing 10 or 20 Iranian bridges a day, day after day, rather than all of them in a sigle day. That would have been a plan he could actually have executed and would at some point have forced the Iranians to do whatever we wanted them to do. Destroying all the bridges in a single day was too severe a penalty for Trump, or any other normal human being, actually to carry it out. So, unless our course is changd, the Iranians will likely avoid any serious punishment.
