The s and u channel decouplet baryon exchange is included explicitly and is found to play a crucial role in understanding the empirical s- and p-wave nuclear kaon dynamics quantitatively.12 pages, 5 figures, invited talk "International Workshop XXVII on Gross Properties of Nuclei and Nuclear Excitations", Hirschegg, Austria, January, 2000Nuclear Theorytext
