Things would have to get very very dire to go the tactical nuke route for the US. Not only is there a fear of tactical nuclear war escalating to strategic war there's the fear of demonstrating tactical nuclear war is feasible. If it works and Iran's nuclear capability is destroyed and nothing else happens then it will be all to easy for another power to use tactical nukes and then nuclear weapons become a common component on the battlefield. That makes escalation to the big strategic weapons easier.
