Firstly, like Realism, Marxist transformative theory assumes that the structure of the international system is an important factor to consider when we want to understand international relations. Whereas realism places emphasis on the anarchic political structure of the world, Marxist transformative theory emphasises the fundamental production (economic) structure and the difference places taken up by states, societies and classes (bourgousesie, proletariat). Some examples: Russia 1920s, workers revolution due to the economic structures put in place by the Monarchy, was an application of the Marxist theory, when it was foreseen that the workers class or proletariat, would assume control.
Marxists also stress power, we saw how realist viewed the distribution as th4e most important explanatory variable in international relations, whereas idealist introduce a range of other factors which can be used to explain the events and tendencies. Here again Marxists transformatists are closer to realist than to idealism, insofar they also highlight power, differentials as an important factor. Big difference: Realists focus on state power in general, specifically on military power (hard power). Marxists tend to emphasise structural economic power.
Thirdly, Marxists transformatists also share realism sceptical attitude towards the role of morality in international relations. Marxists assumes morals are often and ideological smokescreen use to highlight the real and determining economic interests that motivate the behaviour of actors Idealists believe morality plays a huge part in international affairs be kind to your neighbour because it is the right thing to do. Example: America and the Marshall plan giving money to Greece not because it is the right thing to do, but to reduce the invasion of communism and keep the capitalist state alive.
Idealists and Marxists reject realisms almost obsessive pre=occupation with the state. Idealists argue in favour of a plurist point of view, namely that there are many and varied types of actors in international relations. And in the specific context which type of actor plays the dominant role, realism overemphasises the states role. However Marxists are not plurists, they regard only a few types of actors as crucial economic players.
Finally, on the question of whteher international display a basic continuity or not, Marxists transfomatits find themselves between realists and idealist. Like realists, they believe there is not continuity. For Marxists this continuity exists in the fact that throughout history in the fact that throughout that control the means of production and where privilege because of that, while other groups suffered, on the other had, Marxists believe that this basic contiuntiy does not rule out the possibility does not rule out the possibility of fundamental transformation. Like Idealist, Marxists also believe that the world can be made a better place. But, where they differ, is that Marxists do not see this improvement as a natural process, but as something that has to be deliberately done.
