Yep, i remember the remark Lenin made in october 1918, about the impending revolutions in Europe. He said:

Europe’s greatest misfortune and danger is that it has no revolutionary party. It has parties of traitors like the Scheidemanns, Henaudels, Hendersons, Webbs and Co., and of servile souls like Kautsky. But it has no revolutionary party.

Of course, a mighty, popular revolutionary movement may rectify this deficiency, but it is nevertheless a serious misfortune and a grave danger.

And of course, revolutions did happened but failed miserably because instead of revolutionary leaders people found mostly socialchauvinist traitors.
