"Without an understanding of the economic basis of war, no one can be its determined or effective opponent. Sentimental appeals will not hold back a nation inflamed by patriotic lies. Only the man who understands clearly that he is being asked to die for J. P. Morgan's investments abroad, or the markets of the oil and machinery trusts, will be immune to the customary lies about small nations, enemy atrocities, or democracy. That is why it is so necessary to spread a knowledge of Marxian economies; that is why it is so necessary to maintain a clear-cut Marxian platform in politics, based on the realities of the class war. Prepare for the next war! Prepare by studying Marx and Lenin, by studying the Russian Revolution. Prepare to fight Wall Street, instead of dying to protect its wealth. Inoculate yourself against the liberals who will want to lead you into another capitalist war for whatever holy and subtle reason. Prepare against the Walter Lippmanns, the Rabbi Stephen Wises, the Woodrow Wilsons, Spargoes, Bohns, Scheidemanns, Eberts, Kropotkins, Albert Thomases, Arthur Hendersons, of the next war. They are in your midst now; ask them what they will do, SPECIFICALLY, when the nation is mobilized. Prepare."
