                                    Resum

 We address the question of the relation between supersymmetry breaking and
   the origin of flavor in the context of CP violating phenomena. We prove
  that, in the absence of the Cabibbo--Kobayashi--Maskawa phase, a general
    Minimal Supersymmetric Standard Model with all possible phases in the
  soft--breaking terms, but no new flavor structure beyond the usual Yukawa
    matrices, can never give a sizeable contribution to $\varepsilon_K$,
     $\varepsilon^\prime/\varepsilon$ or hadronic $B^0$ CP asymmetries.
  Observation of supersymmetric contributions to CP asymmetries in B decays
   would hint at a non--flavor blind mechanism of supersymmetry breaking.
