2010s, 2016, Donald Trump and the fitness threshold (2016)
Context: Donald Trump, the man who defied every political rule and prevailed to win his party’s nomination, last week took on perhaps the most sacred political rule of all: Never attack a Gold Star family. Not just because it alienates a vital constituency but because it reveals a shocking absence of elementary decency and of natural empathy for the most profound of human sorrows — parental grief.
Why did Trump do it? It wasn’t a mistake. It was a revelation. It’s that he can’t help himself. His governing rule in life is to strike back when attacked, disrespected or even slighted. To understand Trump, you have to grasp the General Theory: He judges every action, every pronouncement, every person by a single criterion — whether or not it/he is “nice” to Trump.
