Terrorist violence designed to prevent compromise instead backfires catastrophically [causal]
What, then, was the overall aim of the O.A.S., in embarking upon what, by the summer of 1961, already looked like a lost cause? In simplest terms, it was to make it impossible for de Gaulle's representatives to govern in Algeria; beyond that, there was little coherent, or unified, thought. Though studiously vague at the time, Salan told the author in 1973: "I thought that we could somehow orient opinion in France towards some kind of solution like South Africa — a kind of Apartheid for Algeria." … But the O.A.S. was, as one of its chroniclers, Paul Henissart, remarks: "a very odd organisation, an uncooked pudding of conflicting freakish ideas and aspirations and principles". … If a common denominator in O.A.S. policy could be arrived at, it was to render peace talks impossible by killing off the remaining "men of good will", the moderates of both sides, and by random outrages against the Muslim population which would create an atmosphere in which neither negotiation nor compromise could exist. In this they would be eminently successful — but it would produce quite the opposite results from those desired.
XREF: Parallels the well-documented failure of anti-peace spoiler violence in other conflicts, where killing moderates tends to radicalize the population rather than demoralize it.
