We review arguments that supersymmetric QCD with N colors and Nf ≥ 0 massive quarks confines. We explain that this remains the case for small soft breakings and small supersymmetric masses for any quarks. These results continue to hold at large N. We then consider these theories with large soft breakings -- real QCD -- describing the problem in terms of the direct computation of the linear potential between a heavy quark and antiquark. We provide naive arguments that confinement persists, and then give a more general treatment. The features required for the naive arguments are generally believed to hold at large N. Extending them to finite N requires only mild assumptions.
