Responding with a brilliant polemic, Leon Trotsky, co-leader of the Russian Revolution, explained that workers would not be won over by minority actions, coupled with predictions that reformist leaders would sell out. Such actions rarely achieve anything. By contrast, calling for united and militant resistance would either expose reformist inaction or bring to the fore reformist indecisiveness when faced with ruling class resistance, as in 1914. Their own experience would thus give workers self-confidence to break with their leaders: a truly revolutionary leap in consciousness.
