I review the status of the calculations for two- and three-nucleon forces and their applications in few-nucleon systems. I also address issues like the quark mass dependence of the nuclear forces and resonance saturation for four-nucleon operators.18 pp, plenary talk, International Nuclear Physics Conference (INPC 2004), Goeteborg, Sweden, June 27 - July 2, 2004Nuclear TheoryHigh Energy Physics - PhenomenologyNuclear Experimenttext
