One cannot be a Marxist without feeling the deepest respect for the great bourgeois revolutionaries who had an historic right to speak for their respective bourgeois “fatherlands”, and, in the struggle against feudalism, led tens of millions of people in the new nations towards a civilised life. Neither can one be a Marxist without feeling contempt for the sophistry of Plekhanov and Kautsky, who speak of the “defence of the fatherland” with regard to the throttling of Belgium by the German imperialists, or with regard to the pact between the imperialists of Britain, France, Russia and Italy on the plundering of Austria and Turkey.
