  Even if the concerns related to the naturalness of the electroweak scale are
repressed, the Higgs mass and stability of the electroweak vacuum do not allow
arbitrarily large supersymmetry breaking scale, $M_S$, in the minimal models
with split or high-scale supersymmetry. We show that $M_S$ can be raised to the
GUT scale if the theory below $M_S$ contains a Higgs doublet, a pair of TeV
scale Higgsino and widely separated gauginos in addition to the Standard Model
particles. The presence of wino and gluino below ${\cal O}(100)$ TeV leads to
precision unification of the gauge couplings consistent with the current limits
on the proton lifetime. Wino, at this scale, renders the Higgsino as
pseudo-Dirac dark matter which in turn evades the existing constraints from the
direct detection experiments. Bino mass scale is required to be $\gtrsim
10^{10}$ GeV to get the observed Higgs mass respecting the current limit on the
charged Higgs mass. The framework predicts, $1 \lesssim \tan\beta \lesssim 2.2$
and $\tau[p\to e^+\, \pi^0] < 7 \times 10^{35}$ years, almost independent of
values of the other parameters. The electroweak vacuum is found to be stable or
metastable. The underlying framework provides an example of a viable sub-GUT
scale theory of supersymmetric grand unified theory in which supersymmetry and
unified gauge symmetry are broken at a common scale.
