The Standard Model contains a natural source for CP asymmetries in weak decays, which is described by the KM mechanism. Beyond εK it generates only elusive manifestations of CP violation in \em light-quark systems. On the other hand it naturally leads to large asymmetries in certain non-leptonic beauty decays. In particular when B0- B0 oscillations are involved, theoretical uncertainties in the hadronic matrix elements either drop out or can be controlled, and one predicts asymmetries well in excess of 10% with high parametric reliability. It is briefly described how the KM triangle can be determined experimentally and then subjected to sensitive consistency tests. Any failure would constitute indirect, but unequivocal evidence for the intervention of New Physics; some examples are sketched. Any outcome of a comprehensive program of CP studies in B decays -- short of technical failure -- will provide us with fundamental and unique insights into nature's design.
