Donald Trump is in every sense a continuation in the contemporary political history of the US Presidency; that of a limited executive branch, elected to sit at the centre of a long chain of more powerful domestic and global interests. Presidents are closer to CEOs, hired for their connections, performative ability, and malleable morality. Trump is both CEO of his own company, and CEO of the US Presidency as a brand.
Just as George Bush's role as President was to rubber stamp and cheerlead the ushering in of a New World Order first conceptualised long before he had even entered politics, Trump has a long list of already formulated policy ideas which are given to him, he simply needs to facilitate their passage into law. Policy formulation is the job of those directly underneath and above him; the likes of Stephen Miller, the Adelsons, the the Saudis, and previously Elon Musk.
Any critical review of 20th and 21st Century American Presidents would see Trump as a very logical successor to a long standing heritage in European/American politics of national socialism rooted in a myth surrounding a exaggerated sense of self i.e national pride, and a defined 'other'.
The only ideological difference between the two main parties today is in relation to the 'other', who must either be 'either liberated or enslaved' in the case of the Democrats, or who must be either enslaved, 'killed or expelled'; in the case of the Republicans.
These two central myths of White American Political history have lost significant power in recent decades, notably as corruption and de-nationalisation have drained the system of so much money that the primary function of taxation in America today is maintaining the national mythology for domestic consumption.
Trump is a response to the collapse of the national myth that the US has a duty to 'liberate' the 'other', in the way that Bush Presidency took to it's extreme both domestically and globally. That leaves only the choice of enslaving (Democrats) or killing them (Republicans).
Trump is historically closer to to the version of Putin at the beginning of his presidency. Political gangsterism becomes the norm the closer a system of government approaches internal collapse, primarily because systemic corruption and external infiltration (whether private capital or foreign actors) has simply reached monstrous proportions.
