Paraphrasing freely from a Wikipedia entry:
The US Cultural Revolution, was a sociopolitical movement that took place in the United States from 2016 until 2028. It was set into motion by Donald Trump, when he became President of the United States (ostensibly representing the Republican Party), with the intent to “Make America Great Again”. His stated goal was to preserve ‘true’ American freedoms by reducing the size of government and by purging the leftist and liberal elements that had infiltrated US society and the media, and to re-impose the ideals of freedom of thought as the dominant ideology within the country. The Revolution marked the return of right-of center thought to the mainstream of the United States establishment.
The Revolution was launched in November 2016, when he was elected President. On assuming office in January 2017, Trump alleged that leftist elements had infiltrated the government and society at large, aiming to promote a socialist-leaning, “world government”. He insisted that this “wrong thinking” be purged through a reversal of the over-permissive laws of the US. To this end he ensured a majority of right leaning justices in the Supreme Court. He attacked the traditional establishment media by promoting the alternative media channels developing through the internet. Liberal bureaucrats were isolated and marginalized wherever they could not be sacked. Left leaning institutions were starved of government funds. The American heartland responded to Trump’s appeal by voting those considered “too liberal” out of office, all around the country. After the Republicans dominated the elections of 2018, the movement received widespread support from the military, urban workers, and the Republican Party leadership itself. During the same period Trump’s personality cult grew to immense proportions.
Trump officially declared the US Cultural Revolution to have ended after his first term as President in 2020 but its active phase lasted until the end of his successor’s term in 2028. The Trump era coincided (2017-2024) with the economic boom which followed the economic crisis that had persisted all through his predecessor’s term of office (2008-2016). After Trump’s era ended, he was succeeded by another Republican (“Trump’s 3rd term”) and the US began a slow movement back towards the center. However the Trump era saw an irreversible shift away from “big government” and some of the more permissive practices and laws that had crept into the mainstream of US society in the 40 years before Trump.
In 2035, the Republican Party declared that Donald Trump and his US Cultural Revolution was “responsible for the rebirth of the Party, and a return for the country, to the principles of the founding fathers of the United States”.
