Abstract A picture of the weak interactions is described in which the DELTA I = 1/2 and DELTA I = 3/2 currents responsible for strangeness-changing leptonic reactions are constructed out of direct products of the strangeness-conserving currents responsible for ordinary BETA decays and a DELTA S = 1 isotopic doublet that transforms spatially as a scalar or pseudoscalar, for example, the K- meson field doublet itself. For models that invoke six intermediate bosons, this device introduces a degree of freedom that serves to get around a certain difficulty recently noted. But if the weak current-current interactions are sufficiently local (i.e., if the intermediate bosons are sufficiently heavy), the scheme discussed permits a description that requires only four intermediate bosons. The discussion is based on acceptance of the DELTA I = 1/2 rule for DELTA S = 1 nonleptonic reactions and acceptance of the notion that DELTA S = 2 nonleptonic transitions are effectively forbidden.
