How many times have pundits said "now he is presidential" only to see him act like a child a few minutes later.
I could be wrong but I thought that the ironic message of LotF is that the children are unsettled by the absence of civilization and the normal order of the day which ironically parallels the war, that human civilization is only thinly removed from chaos.
So the question would be is this an example of a noble leader that approaches his own destruction because of a fatal flaw or is it like the unravelling of an entire civilization because the basic rules suddenly evaporate.
I believe that the destruction of Greece is because the Greek Constitution gives the billionaire shipping tycoons and capital gains in the Greek Stock Market tax free status. When the doctors, lawyers and small time business owners see the people at the top exempted from taxes they take a logical next step and cheat on their taxes which pushes the Greek government into bankruptcy that is now subsidized by the adults in France and Germany.
If Trumps assault on the Constitution is not contained and he can personally profit from ignoring the rule of law it will give permission for everyone to abandon the rules of civilization and everyone will be looking for ways of personal enrichment and validation from the pig's head.
Another parallel is that"LotF" paints a society where the loss of civilization creates a vacuum and in the vacuum fear of the beast becomes the organizing principle of society. Unlike the Shakespeare play Trump is trying to personalize power by igniting fear, fear of the terrorist, fear of the undocumented worker, fear of the other.
