A nation is not a natural community that existed before the state, but that it's the other way around: the state existed first and then proceeded to impose on those it ruled over the idea that they formed a “nation”. States pre-existed and in a very real sense created nations. Nations are groups of people ruled by a state or a would-be state. The Polish nationalist Pilsudski observed that "It is the state that makes the nation, not the nation the state." What is a nation? It is simply the people and the territory which have been appropriated by a class of robbers at some point in history. It has less to do with a common language, religion, race, culture, and all the other things which nationalists imagine or pretend are essential ingredients in the making of nations.
All this of course benefits the ruling class. If the workers were ever to put their passion into something like socialism, then it would be the end of the ruling class. It benefits them to see the workers placing meaning and identity in things that are irrelevant and mythical to the truth of class struggle. Keeping the workers unable to see the true state of affairs in the world works to the ruling class's advantage.Class existed before the nation state. Throughout history one ruling class or another has attempted to impose its view on those they ruled over, manipulating their passions and pretending that its interests and their interests were the same. So, in another of life's ironies, the masses waste their energy fighting amongst themselves, believing their interests and the interests of their rulers are linked. Nationalism has always been one of the biggest poisons for the working class. It has served to divide workers into different nation states not only literally but ideologically. Today it is probably fair to say that a majority of workers—to one extent or another—align themselves to their domestic ruling class.Historically, nationalism and national feeling have been the tool of the capitalist class for both winning and retaining power. The ruling class have cultivated such ideas as nationalism, propagating the illusion that we live in a society with a collective social interest. The more enlightened capitalists probably saw the effects of separating and alienating people from each other and their labour, and so stepped up the spreading of beliefs like nationalism in order to try and convince people that they were not so exploited as they really were, and that everyone had a common interest.
To the Socialist Party, class consciousness is the breaking-down of all barriers to understanding. The conflict between the classes is more than a struggle for each to gain from the other: it is the division which reaches across all others. The class-conscious working person knows where one stands in society. His or her interests are opposed at every point to those of the capitalist class. Nationalism is not their interest but their rulers'. The presence of nationalist ideas is an indication that some groups in society feel its real material interests are being frustrated by forces outside or even inside the nation. But the desire to achieve their aims is never expressed in terms of their own needs only. In order to enlist the necessary working class support such arguments as “justice”, “freedom”, and “the nation” are used to justify the real bone of contention and to give it an aura of sanctity.The concept of nationality, the idea that an area dominated by a privileged class which thrives on the enforced poverty of that area's productive class, should grant to the latter the right to live there providing its members accept their wage-slave status and endorse the right of the privileged to live on their backs is offensive to any intelligent person. Those who promote such nonsense are enemies of our class.
As socialists we re-affirm that all peoples should seek their emancipation, not as members of nations or religions or ethnic groups, but as human beings, as members of the human race. They should unite to abolish the division of the world into so-called nation-states and to establish a World Cooperative Commonwealth of which we will all be free and equal members - citizens of the world, not subjects of nation-states. The goal of the socialist movement is not to assist in the creation of even more states but to establish a real world community without frontiers where all states as they currently exist will be destroyed. In a socialist society communities, towns and cities will have the opportunity to thrive – and people will no doubt feel an attachment to places that are real and tangible – but the nation states will be consigned to the history books where they belong.
