> In a sense, this is an example of the US responding in kind to something that Europe has already done.

Is this meant to be funny ? /s

Seems like a kiddy moral statement. Europe has done so many bad things in the past, but US currently has the lead !

This affair learns us some interesting things :

1) nation states are the current structure that defends people, a statement which was challenged by the creation of EU, and will try to protect their people before others.

2) Global trade cannot abolish the aforementioned statements.

Pick your conclusion. Mine currently is :

States have lost self-reliance based on global trade doctrine and this trend should be reversed. Chicago school has made enough ravages.
