Neoconservative columnist Robert Kagan warned in a Washington Post column (http://www.businessinsider.com/robert-kagan-trump-2016-5) published May 19, 2016, that the "Republican Party's attempt to treat Donald Trump as a normal political candidate would be laughable were it not so perilous to the republic.” and that Trump could be putting America on a path to "fascist” rule.
"Trump has transcended the party that produced him," Kagan wrote. "His growing army of supporters no longer cares about the party. ... Their allegiance is to him and him alone.”
In both republican and imperial Rome, contending factions were often allied with popular generals whose independent armies wrestled for control of regions or greater Rome itself for hundreds of years. Many of them used the traditional “fasces” (https://en.wikipedia.org/wiki/Fasces) as a symbol of their power and legitimacy. In the end, these internecine battles came to be more important than the defense of the empire, which was then dismembered by marauders from the margins.
In 1920s Russia and Italy, 1930s Germany, Japan, Spain…, one dictator after another came to power somewhat legitimately and then consolidated its power into an absolute form. Those countries are now in the fourth and fifth generation of atonement for their past. Italy’s political, religious and social fragmentation has lasted for 1,500 years.
The substitution of personal for national loyalty is always and unambiguously a threat to any political system. We are not immune. Kagan’s observations are especially noteworthy due to his conservative orientation and illustrate the nexus of conservatism and liberalism that have traditional formed the core of our transcendant national principles.
