The PAGS party ceased all activity in 1992 and Hadjeres himself left Algeria and settled in France where he undertook works as associate lecturer and researcher in geopolitics with the CRAG center of Paris 8 University (Centre de recherches et d’analyses géopolitiques à l'Université de Paris VIII). He published several articles in the journal Hérodote and gave talks at colloquiums and study conferences, as well as publishing articles in the Algerian and international press, and prepared books on the evolution of the national and social Algerian movements, starting with the PPA crisis of 1949.
