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