Words on their own are meaningless. The success of a political interest participating in dialogue is a function of both its political power and the character of its relationship with the relevant different political powers. It is not a function of its debating skills. If the Provos had no political power the Irish, British and American bourgeois governments would not have given it anything like the attention it has received. Again for Adams dialogue produced the IRA ceasfire.
Words take on the power of concrete struggle.
The armed struggle of the IRA generated dialogue, words, and these words in turn generated the IRA ceasefire. Adam's mystifies the power of words. He is the prisoner of words and images. The real situation is that the Provos ceased their armed struggle because of concrete political considerations and not because of mere dialogue. The very fact that the IRA found it necessary to end the ceasefire is proof of the limitations of dialogue, of language.
