In the first months after the proletariat in Russia had won political power (October 25 [November 7], 1917), it might have seemed that the enormous difference between backward Russia and the advanced countries of Western Europe would lead to the proletarian revolution in the latter countries bearing very little resemblance to ours. We now possess quite considerable international experience, which shows very definitely that certain fundamental features of our revolution have a significance that is not local, or peculiarly national, or Russian alone, but international. I am not speaking here of international significance in the broad sense of the term: not merely several but all the primary features of our revolution, and many of its secondary features, are of international significance in the meaning of its effect: on all countries. I am speaking of it in the narrowest sense of the word, taking international significance to mean the international validity or the historical inevitability of a repetition, on an international scale, of what has taken place in our country. It must be admitted that certain fundamental features of our revolution do possess that significance.
It would, of course, be grossly erroneous to exaggerate this truth and to extend it beyond certain fundamental features of our revolution. It would also be erroneous to lose sight of the fact that, soon after the victory of the proletarian revolution in at least one of the advanced countries, a sharp change will probably come about: Russia will cease to be the model and will once again become a backward country (in the "Soviet" and the socialist sense).
At the present moment in history, however, it is the Russian model that reveals to all countries something—and something highly significant—of their near and inevitable future. Advanced workers in all lands have long realised this; more often than not, they have grasped it with their revolutionary class instinct rather than realised it. Herein lies the international "significance" (in the narrow sense of the word) of Soviet power, and of the fundamentals of Bolshevik theory and tactics. The "revolutionary" leaders of the Second International, such as Kautsky in Germany and Otto Bauer and Friedrich Adler in Austria, have failed to understand this, which is why they have proved to be reactionaries and advocates of the worst kind of opportunism and social treachery. Incidentally, the anonymous pamphlet entitled The World Revolution (Weltrevolution), which appeared in Vienna in 1919 (Sozialistische Bucherei, Heft 11; Ignaz Brand), very clearly reveals their entire thinking and their entire range of ideas, or, rather, the full extent of their stupidity, pedantry, baseness and betrayal of working-class interests—and that, moreover, under the guise of "defending" the idea of "world revolution".
We shall, however, deal with this pamphlet in greater detail some other time. We shall here note only one more point: in bygone days, when he was still a Marxist and not a renegade, Kautsky, dealing with the question as an historian, foresaw the possibility of a situation arising in which the revolutionary spirit of the Russian proletariat would provide a model to Western Europe. This was in 1902, when Kautsky wrote an article for the revolutionary Iskra,  entitled "The Slavs and Revolution". Here is what he wrote in the article:
"At the present time [in contrast with 1848] it would seem that not only have the Slavs entered the ranks of the revolutionary nations, but that the centre of revolutionary thought and revolutionary action is shifting more and more to the Slavs. The revolutionary centre is shifting from the West to the East. In the first half of the nineteenth century it was located in France, at times in England. In 1848 Germany too joined the ranks of the revolutionary nations.... The new century has begun with events which suggest the idea that we are approaching a further shift of the revolutionary centre, namely, to Russia.... Russia, which has borrowed so much revolutionary initiative from the West, is now perhaps herself ready to serve the West as a source of revolutionary energy. The Russian revolutionary movement that is now flaring up will perhaps prove to be the most potent means of exorcising the spirit of flabby philistinism and coldly calculating politics that is beginning to spread in our midst, and it may cause the fighting spirit and the passionate devotion to our great ideals to flare up again. To Western Europe, Russia has long ceased to be a bulwark of reaction and absolutism. I think the reverse is true today. Western Europe is becoming Russia’s bulwark of reaction and absolutism.... The Russian revolutionaries might perhaps have coped with the tsar long ago had they not been compelled at the same time to fight his ally—European capital. Let us hope that this time they will succeed in coping with both enemies, and that the new ’Holy Alliance’ will collapse more rapidly than its predecessors did. However the present struggle in Russia may end, the blood and suffering of the martyrs whom, unfortunately, it will produce in too great numbers, will not have been in vain. They will nourish the shoots of social revolution throughout the civilised world and make them grow more luxuriantly and rapidly. In 1848 the Slavs were a killing frost which blighted the flowers of the people’s spring. Perhaps they are now destined to be the storm that will break the ice of reaction and irresistibly bring with h a new and happy spring for the nations" (Karl Kautsky, "The Slavs and Revolution", Iskra, Russian Social-Democratic revolutionary newspaper, No. 18, March 10, 1902).
How well Karl Kautsky wrote eighteen years ago!
 The old Iskra—the first illegal Marxist newspaper in Russia. It was founded by V. I. Lenin in 1900, and played a decisive role in the formation of revolutionary Marxist party of the working class in Russia. Iskra’s first issue appeared in Leipzig in December 1900, the following issues being brought out in Munich, and then beginning with July 1902—in London, and after the spring of 1903—in Geneva.
On Lenin’s initiative and with his participation, the editorial staff drew up a draft of the Party’s Programme (published in Iskra No. 21), and prepared the Second Congress of the R.S.D.L.P., at which the Russian revolutionary Marxist party was actually founded.
Soon after the Second Congress, the Mensheviks, supported by Plekhanov, won control of Iskra. Beginning with issue No. 52, Iskra ceased to be an organ of the revolutionary Marxists.
