The political spectrum is the basis to chart and navigate political views from socially liberal and libertarianism to authoritarian left and authoritarian right.
The political view on the political left tends to be more liberalistic (if you are focusing on the libertarians’ side of it) and socially progressive supporting big government and state welfare to create a “utopia” society where labor isn’t required to put a meal on the table and other issues, whereas authoritarian left like communism, and syndicalism and Marxism and socialism tend to be socially conservative while maintaining progressive views on economic issues and hierarchy but overall still has the belief that all are equal in a sense though when executed in real life tends to fall short.
Libertarian right tends to be more socially conservative and economically progressive allowing basically anything to fly if it is for the means of making money and upkeeping the status quo of supply and demand, and authoritarian right tends to be more focused on views like social equality via a homogenous society and tends to incorporate expansionism for either purposes like ultra nationalism or to gain resources for a society, nation and its peoples. Often times Authoritarian right and left tend to overlap like with National Socialism in Germany or Italian Fascism (national syndicalism) in Italy, but can also be imperial/monarchial rule like with the Japanese empire or other historical empires and kingdoms.
Authoritarian governments have the view of either expansionism either territorial or industrial, either to restore a feeling of greatness and prides to the parties people, or to create a stable future for the government, whereas Libertarianism ideals tend to be more greed to power towards the people at the expense of the people by allowing a either high tax society or a market competitive society and social issues being addressed like inequality and closing wealth gaps.
The government of the book of 1984 seems to fall between authoritarian left and right seeming to blend ideals of National Socialism with Marxist ideals like total equality and the also never ending war between the nations of Eurasia and Oceania which shows that the government of the book is an amalgamation of political views.
