Query: Hadron-Hadron Interactions   The present status of the chiral approach to the $NN$ interaction as proposed
by Weinberg is discussed. The important role of correlation effects and
explicit vector meson ($\rho$, $\omega$) exchange in the dynamics of
baryon-baryon interactions is demonstrated. As an example, the inclusion of the
exchange of a correlated pair of $\pi$ and $\rho$ meson between two nucleons
appears to be mandatory in order to resolve a long-standing puzzle concerning
the formfactor at the pion-nucleon-nucleon vertex.
