Would be better if he made more explicit what the alternative to this "anti-colonial" liberal trend was. I can see his practical argument but I also still don't know if the settler proletariat will not be in contradiction with the colonized proletariat yet.

Solidarity between the two sides of the international proletariat is materially sacrificial, it's hard to imagine building a movement on sacrifice
