“After the war the US monopoly capitalists were confronted with a vital problem: how to maintain their colossal munitions industry, and what to do with their tremendous amount of surplus capital.
The US imperialists clamoured about a ‘communist threat’ in order to provide an excuse for continuing to expand their munitions industry, adopted the policy of a cold war that was directed against the socialist countries and increased international tension, under the pretext of protecting the ‘free world.’ This was essentially the ‘Truman Doctrine.’ Meanwhile, in order to avoid an economic crisis and dispose of their surplus capital, they carried out the policy of gaining hold of the economies of the major capitalist countries in Europe by means of captial investment in the name of ‘aiding’ their economic recovery from the ravages of war. This was what they called the ‘Marshall Plan.’
In this way US imperialism acquired a firm grip on the capitalist world militarily and controlled it economically, while clinging more and more to an aggressive policy in order to check the growing socialist forces and materialize its ambition for world conquest. Drawing on developed technology and superior economic strength the monopoly capital of the United States intensified its inroads into other countries and estabished multinational companies by setting up daughter companies in various countries. In the 1960s many multinational companies based in the other developed capitalist countries also appeared. Thus the internationalization of capital was accelerated and the economies of the capitalist world were brought under the domination of the multinational companies of the US and other developed capitalist countries.
Wih the rapid internationalization of capital through multinational companies, new changes took place in the mutual relations between capitalist countries.
Before the Second World War the capitalist powers engaged in fierce competition to seize commodity markets and spheres of influence, and this led to destructive armed clashes and wars. It can be said that both the First and Second World Wars were the results of the sharpening contradictions and antagonism between the capitalist powers. As the internationalization of capital prgressed after the Second World War, however, the capitalist powers depended on and collaborated with each other economically and technically.
Previously they had expanded great energies on competing with and defeating each other, but, from that time onwards, they joined hands to oppose socialism and intensify capitalist exploitation and plunder. It might be said that the greatest change in the capitalist world since the Second World War has been the capitalist powers have gone over from dog-eat-dog relations to those of alignment and cooperation. Of course, this does not mean that no contradiction exists between the capitalist powers, but now this is of secondary importance and alignment is the basis of their relations. During the 40 years since the end of the Second World War there have been more than 170 wars, major and minor, but none of them has been fought between capitalist powers themselves; rather their military alignment has been strengthened through military blocs.
As a result of capital being internationalized and of world imperialism having realigned itself, centering on US imperialism, capitalism has survived its imminent doom and made rapid economic and technical progress.
Since the end of the Second World War the imperialists have not only aligned themselves with each other politically, economically and militarily, but also evolved more cunning techniques of domination and crafty methods of plunder. This is also an important feature of contemporary imperialism.
The imperialists could not help being extremely alarmed at the rapidly-growing socialist forces and the upsurge of the working-class movement and national-liberation movement in the colonies. That is why they have devised new and more cunning techniques of ruling and crafty methods of plundering to weaken the influence of socialism and appease the working-class movement and national-liberation movement in the colonies.
The imperialists were keenly aware of the fact that they would not be able to maintain the capitalist system unless the working-class movement in their own countries was undermined, so they brought up large numbers of labor aristocrats, while striving to conceal capitalist exploitation and to subdue the resistance of the working masses through unemployment and poverty. ”
