  The parity-violating nucleon-nucleon interaction is the key to understanding
the strangeness-conserving hadronic weak interaction at low energies. In this
brief talk, I review the past accomplishments in and current status of this
subject, and outline a new joint effort between experiment and theory that
tries to address the potential problems in the past by focusing on parity
violation in few-nucleon systems and using the language of effective field
theory.
