I must remember my lunchtime insight on Foucault, and write about it. His message is that you have lost, and you can analyze this but resistance is futile. I thought it as a freshman, reading him in the French Library as person upon person renounced militancy, and I am thinking it again.
The other point to be noted, and people were talking about it the other day, is that Foucault and Derrida were not the first to criticize colonialism. So people who say that thanks to these two, they were able to do it, are of a certain stripe.
