It’s hard to argue that an eye-for-an-eye response is unjustified, sure. But it’s easy to see that, in a conflict, direct, equivalent retaliation is often the least strategic response. It signals desperation (which reveals weakness), and also legitimizes your opponent’s actions. It hurts your political capital (allies lose confidence in you), which is a vital tool (e.g. coordinated international show of political/trade force). Given the current US leadership, though, it’s not surprising they’d press any button they can reach.
