In Algeria, for reference, the French as with colonialists everywhere invaded a place, took the majority of the land from the people actually living there, and reduced them to third-class citizens of their own country. The de-colonization war here was one of the more brutal wars of national liberation, but both the conquest and the war of liberation had sometimes curious legacies (such as the 19th Century America fetish for Zouaves and Yasser Arafat's using Algeria as an example for his attempts to destabilize Jordan and Lebanon). I think that he stopped short of a full apology, in contrast to the USA's actions with regard to slavery and the treatment of Native Americans does illustrate an interesting contrast between French and US political attitudes to historical injustice.
I do think that it's both sad and typical, however, that it's the socialist French who can at least admit to the blindingly obvious but that they don't go anywhere near far enough as the situation would seem to warrant. What say you?
