Query: Alternative Solution of Strong CP   In this talk I begin with some general discussion of the history of CP
violation, then move on to aspects of a spontaneous CP violation model
including the production of new particles at LHC, implications for B decay,
generalized Cabibbo mixing and a reevaluation of kaon CP violation. Finally
there is a summary.
