In Rwanda, France is playing on the side of the angels. No one gives Rwanda much attention. You can't care about everything. The butchery there and in Burundi was the single most despicable act of genocide in recent history and there has been some pretty hot competition for the title.

When there are monsters around, you can (a) ignore them and let them get away with; (b) invade; (c) organise international action to hold murderous thugs to account for crimes against humanity anywhere in the civilised world.

The last option is the only good one.
