Arguments based on unitarity indicate that hadronic loop diagrams should produce large violations of the Okubo-Zweig-Iizuka rule. The mechanism by which these corrections are evaded has long been a mystery. We have found that there is an exact cancellation of all such loops in a particular limit and that, at least for the rho - omega - phi system which we have studied in detail, the cancellation is maintained in a realistic calculation which takes into account departures from this limit.
