In contrast to this, Challe adopted as his guiding principle the slogan "Neither the djebel nor the night must be left to the F.L.N." Once hit, a rebel unit must be hit again, and remain hit; the army must penetrate the querencia where—like a fighting bull—it was at home, and stay there, driving it out into unknown and unfriendly territory. Life must be made enduringly unendurable for the moudjahiddine. The hunter must become the hunted. … Disruption, not annihilation, which he considered to be unattainable, was Challe's objective; above all, the rebel O.P.A. (Organisation Politico-Administrative) had to be so smashed that it could not reestablish itself once the offensive wave had receded.

DEFINE: Challe's strategy is defined by contrast between disruption and annihilation, and introduces the O.P.A. term.
