This may be true relatively, so long as the oppressed, and chiefly the workers, have no self-consciousness, fail to recognize the injustice of their oppressors. There is, then, the dominating class only that counts; and this class, owing to its desire to conserve and to enlarge its power, even its prejudices and its own ideas, may find it convenient to excite racial ambitions and hatred, and send its nation, its flock, against "foreign" countries, with a view to releasing them from their present oppressors, and submitting them to its own political economical domination."
