  We analyze the minimal supersymmetric left-right model with
non-re\-nor\-malizable interactions induced by higher scale physics and study
its {\it CP} violating properties. We show that it: (i) solves the strong {\it
CP} problem; (ii) predicts the neutron electric dipole moment well within
experimental limits (thus solving the usual SUSY {\it CP} problem). In
addition, it automatically conserves {\it R}-parity. The key points are that
the parity symmetry forces the Yukawa couplings to be hermitean, while
supersymmetry ensures that the scalar potential has a minimum with real higgs
doublet vacuum expectation values. Gluino and B-L gaugino masses are
automatically real. The observed {\it CP} violation in the kaon system comes,
as in the Standard Model, from the Kobayashi-Maskawa-type phases. These
solutions are valid for any value of the right-handed breaking scale $M_R$, as
long as the effective theory below $M_R$ has only two Higgs doublets that
couple fully to fermions. ({\it i.e.} the theory below $M_R$ is MSSM-like.) The
potentially dangerous $SU(2)_L$ gaugino one-loop contributions to
$\bar{\Theta}$ below $M_R$ can be avoided if the left-right symmetry originates
from a unified theory in which the $SU(2)_{L,R}$ gaugino masses are real. As an
example, we show how the left-right symmetry can be embedded in an SO(10)
theory.
