"“ Left nationalism, organised under the Forward Bloc, was born as an independent political force five months before the war. Five months of rapidly marching events after the outbreak have turned it into its very opposite and left it neither as genuine leftism nor good nationalism. It acts not as a progressive but as a retrogressive force. Its words are Left, its practice is anti-struggle, anti-unity, its aim remains settlement with imperialism."
