I suspect that the word "Jingoism" is no longer taught in the public schools. 

 If so, the Trump rhetoric would have produced it by now.  

And it is such a useful word when you have the likes of Putin, the North Korean regime, the Chinese and so forth running amok and Trump pursuing his international agenda.

I also believe that the internal US focus on multi-culturalism as opposed to international concerns after the fall of the USSR accounts for that.  Then, when you get a Putin or a Kim or even a Trump, you have no context for evaluation.
