Momentarily, Algeria seemed to recede from the limelight, but meanwhile, all the time, unseen pressure from the syndicalistes and the “respectable” Left was mounting for de Gaulle to initiate peace negotiations in earnest with the F.L.N. The growth of war-weariness in France was becoming particularly apparent; that is, apparent to all but those army leaders now bent upon eliminating de Gaulle so as to continue the struggle to “save” Algeria. For, inept and ineffectual as it had been, the would-be coup in December 1960 had marked a crossing of the Rubicon. Sections of the French army were now irretrievably committed to revolt against the head of state in all his authority, and to all that so grave a commitment signified.

XREF: The 'crossing of the Rubicon' framing and irretrievable commitment to revolt evoke parallels with military loyalty crises elsewhere, such as the 1981 Spanish coup attempt or other civil-military tensions.
