The need for a spontaneous N=2 supersymmetry breaking is emphasized, because of its possible relevance in the search for an ultimate theoretical solution to the confinement problem.7 pages, LaTeX, macros included (Talk given at the 31st International Ahrenshoop Symposium on the Theory of Elementary Particles, 2-6 September 1997, in Buckow, Germany, and the String Workshop, 14-15 November 1997, in Wittenberg, Germany)High Energy Physics - Theorytext
