LENIN'S BALANCE AND INSIGHT : BEAT THE BUSHES BUT WATCH FOR THE SWAMP, by Andrew Taylor, Oct 30, 2009

The more powerful enemy,” Lenin said, “can be conquered only by exerting the utmost effort, and by thoroughly, carefully, attentively, and skillfully taking advantage of every, even the smallest, “rift” among the enemies, … among the various groups of bourgeoisie …, by taking advantage of every, even the smallest, opportunity of gaining a mass ally, even though this ally may be temporary, vacillating, unstable, unreliable, and conditional.

"Social-chauvinism and opportunism are the same in their political essence; class collaboration, repudiation of the proletarian dictatorship, rejection of revolutionary action, obeisance to bourgeois legality, non-confidence in the proletariat, and confidence in the bourgeoisie. The political ideas are identical, and so is the political content of their tactics. Social-chauvinism is the direct continuation and consummation of Millerandism, Bernsteinism, and British liberal-labour policies, their sum, their total, their highest achievement. "
