People always have been the foolish victims of deception and self-deception in politics, and they always will be until they have learnt to seek out the interests of some class or other behind all moral, religious, political and social phrases, declarations and promises.
Lenin, The Three Sources and Three Component Parts of Marxism
Is it true that, in general, the economic struggle “is the most widely applicable means” of drawing the masses into the political struggle? It is entirely untrue. Any and every manifestation of police tyranny and autocratic outrage, not only in connection with the economic struggle, is not one whit less “widely applicable” as a means of “drawing in” the masses. The rural superintendents and the flogging of peasants, the corruption of the officials and the police treatment of the “common people” in the cities, the fight against the famine-stricken and the suppression of the popular striving towards enlightenment and knowledge, the extortion of taxes and the persecution of the religious sects, the humiliating treatment of soldiers and the barrack methods in the treatment of the students and liberal intellectuals — do all these and a thousand other similar manifestations of tyranny, though not directly connected with the “economic” struggle, represent, in general, less “widely applicable” means and occasions for political agitation and for drawing the masses into the political struggle? The very opposite is true. Of the sum total of cases in which the workers suffer (either on their own account or on account of those closely connected with them) from tyranny, violence, and the lack of rights, undoubtedly only a small minority represent cases of police tyranny in the trade union struggle as such. Why then should we, beforehand, restrict the scope of political agitation by declaring only one of the means to be “the most widely applicable”, when Social-Democrats must have, in addition, other, generally speaking, no less “widely applicable” means?
Lenin, What Is To Be Done?
But what else is the function of Social-Democracy if not to be a “spirit” that not only hovers over the spontaneous movement, but also raises this movement to the level of “its programme”? Surely, it is not its function to drag at the tail of the movement. At best, this would be of no service to the movement; at worst, it would be exceedingly harmful. Rabocheye Dyelo, however, not only follows this “tactics-as-process”, but elevates it to a principle, so that it would be more correct to describe its tendency not as opportunism, but as tail-ism (from the word tail).
Islamic State claimed responsibility for the attack late on Friday, in a post on Telegram in which the group claimed its gunmen had managed to escape afterwards.
