Challe's programme was to declare solemnly that the French army's unshakable intention was to remain in Algeria, and then re-launch a new flat-out "Challe Offensive" against the A.L.N., mobilising eight classes of Algerians of both races for this purpose. In three months he would present France a pacified Algeria, sur le plateau. He hoped, in effect (comments Jacques Fauvet): "to finish what two regimes, four commanders-in-chief and seven governments were unable to finish in seven years". During this period of three months, a breakaway Algeria could exist economically off the fat of its oil resources, an embargo being placed on their export to France. For the long-term political future of Algeria, Challe basically supported a return to the principles of Lacoste's abandoned loi-cadre.

QUESTION: How did Algerian oil resources compare to France's dependence at the time? Worth exploring the economics of the embargo threat.
