So .. there are a couple of angles. Whether Iran, officially as a nation, retaliates is one. Whether some terrorist group, funded by Iran or not, retaliates is separate. I would be a bit surprised if the nation of Iran attempts retaliation because they are a fixed target, immobile, easy to hit. I would expect them to behave more rationally. A terrorist group imbedded within some population somewhere else retaliating / striking a blow to get even, in their perception, seems a lot more likely. I would be cautious traveling abroad or doing business abroad, but then, that is already true.
