One other advantage about the approach to empire and colonialism adopted in our four books is that it takes colonialism–and especially fascism–as a (racist and violent) solution to a real crisis. Thus this crisis does not simply disappear with the end of the war or the retreat of the colonial power. If and how this crisis reappears, in what form, in what register, and how it might be solved in a post-colonial context is immediately an urgent issue.
For an example from Ireland of the debate and the difference between a political revolution and a social revolution see 1:28:38 to 1:30:00 of The Wind that Shakes the Barley. The longer scene, and the whole movie is very good on this, too. Highly recommended but not required.
