  We argue that with the discovery of neutrino mass effects at Super-Kamiokande
there is a clear logical chain leading from the Standard Model through the MSSM
and the recently developed Minimal Left Right Supersymmetric models with a
renormalizable see-saw mechanism for neutrino mass to Left Right symmetric SUSY
GUTS : in particular, SO(10) and $SU(2)_L \times SU(2)_R\times SU(4)_c$. The
progress in constructing such GUTS explicitly is reviewed and their
testability/falsifiability by proton decay measurements emphasized.
