Yes, Il Trumpe actually said that to a grieving war widow. First, it just shows that Trump isn’t just a narcissist, but that he, due to his wealth and privilege, has not had to hide his narcissism for a very long time (and he also created an environment which encouraged his narcissism). Like many of Trump’s utterances, this is designed largely for his consumption, to validate his own sense of well-being: he says this, so it’s not his fault.
Second, we need to stop fighting all of our wars. We’ve reached the point where traditional college seniors have no recollection of what it’s like for the U.S. not to be in multiple combat theaters (or even one). Our constant state of war is incredibly harmful in so many ways, and those of us (including me) who remember when we weren’t at constant deployment need need to do more to remind people of this.
