Since the report on the class struggle to the last Congress, there have been no immediate shifts in the overall situation facing the class. The proletariat has demonstrated, through various struggles, that its combativity remains intact and that its discontent is growing (eg transport workers in New York, 'general strike' in Norway, struggles in numerous sectors in France, postal workers in Britain, movements in peripheral countries like Brazil, China, etc). But the situation continues to be much more clearly defined by the difficulties facing the class - difficulties imposed by the conditions of decomposing capitalism but continually reinforced by the bourgeoisie's ideological campaigns about the 'end of the working class', the 'new economy', 'globalisation', and even 'anti-capitalism'. Within the proletarian political milieu, meanwhile, there remain fundamental disagreements about the balance of class forces, with certain groups using the ICC's 'idealist' view of the historic course as a reason for not participating in any joint initiative against the war in Kosovo. This is certainly one reason to focus this report not so much on the struggles of the recent period, but on trying to deepen our understanding of the concept of the historic course as it has developed in the workers' movement: if we are to answer these criticisms effectively, we must obviously go to the historical root of the misunderstandings that infect the proletarian milieu. Another reason is that one of the weaknesses in our own analyses of recent struggles has been a tendency towards immediatism, a tendency to concentrate on particular struggles as 'proof' of our position on the course, or on the difficulties of the struggle as a possible basis for calling our conceptions into question. What follows is very far from an exhaustive survey; it's main aim is to assist the organisation to acquaint itself more closely with the general method through which marxism has approached this question.
